Hair loss in women - how to prevent it and which supplement really works?

Hair loss affects an increasing number of women, regardless of age, lifestyle or health condition. For many of them, thinning strands, an increasingly wider parting and a handful of hair on the brush cause stress and prompt them to look for quick, effective solutions. If this problem affects you, you will find a lot of valuable information here: the most common causes of excessive hair loss, tips on which tests to do, how to take care of your diet and which supplements may effectively support hair growth.
Hair loss, a sensitive problem for many women
Hair loss in women is a bigger problem than it might seem. It affects new mothers after childbirth, women struggling with hormonal disorders, women after intense stress, as well as those in the perimenopausal period. It often starts innocently - a little more hair on the brush, slight thinning above the forehead. Unfortunately, this can sometimes lead to reduced self-confidence and discomfort in everyday life.
In this situation, women ask themselves, “what should I choose for hair loss?”. They look for hair tablets or comprehensive vitamins for skin, hair and nails. However, a poorly matched supplement will not bring results.
That is why we have prepared a complete guide for you, which explains step by step what really works for hair loss, which vitamins for hair, skin and nails are key, what mistakes we most often make and what professional diagnostics look like. Most importantly, we discuss effective supplementation in it. In addition, at the end you will find a practical action plan and a short FAQ with the most frequently asked questions.
When does hair loss in women become a problem?
How much hair can fall out per day – what is normal?
Physiologically, we lose about 50–100 hairs every day, which is a completely natural stage of the growth cycle of each hair. The problem begins when you notice a clearly larger amount of fallen-out hair during washing, on the pillow, or when the strands suddenly become much thinner and much weaker than before. This may mean it is time to take better care of yourself.
Symptoms of excessive hair loss in women
Warning signs that should be given particular attention include:
- a visibly thinning parting,
- increasingly visible receding hairline,
- diffuse alopecia (thinning hair across the entire head),
- whole clumps of hair coming out during combing and staying on the brush.
If you notice such symptoms, this may already indicate excessive hair loss that requires specific action. It is worth considering changing your hair care habits and supplementing with appropriate products.
When should you definitely see a doctor or trichologist?
If the problem lasts longer than 2-3 months, your hair is falling out in handfuls, or you suspect hormonal disorders, thyroid disease or iron deficiencies – a medical or trichological consultation may be necessary. Remember that many methods, including supplementation, are important support, but they will not replace treatment of medical causes. It is therefore worth knowing the cause of hair loss so as not only to alleviate the symptoms, but to address its more deeply rooted reason.

The most common causes of hair loss in women
Hormones and hair loss in women (menopause and estrogen dominance)
Hormones are one of the most important factors regulating the hair growth cycle. In the perimenopausal period, the decrease in estrogens causes thinning and slower regrowth, which may contribute to the appearance of thinning hair. In turn, progesterone disorders or estrogen dominance also affect increased shedding. It is worth paying attention to this. If you are not in menopause, it is a good idea to have hormone tests done to make sure your results are within the normal range. This way you will confirm or rule out hormonal disorders as the cause of problems related to hair loss.
Hair loss after childbirth and during pregnancy
Hair loss in women after pregnancy is one of the most common problems – so-called postpartum alopecia, resulting from a sudden drop in estrogens. Although it is physiological, it can last even 6-12 months. If this time is prolonged, it is worth going for a medical consultation.
Thyroid and hair (Hashimoto’s, hypothyroidism and hyperthyroidism)
Hair loss in women and the thyroid – what do they have in common?? Thyroid disorders very often cause hair loss. Once a year, it is a good idea to have blood thyroid hormone tests done to check whether all parameters are fine. Hashimoto’s, hypothyroidism and hyperthyroidism lead, among other things, to slower hair regeneration, brittleness and loss of shine.
Stress, unhealthy lifestyle and lack of sleep
Cortisol disrupts the anagen phase, i.e. hair growth, leading to weakened hair bulbs. A high level of stress therefore has a major impact on more intense hair loss. An unhealthy lifestyle, lack of a balanced diet, an excess of stressful situations, and limited sleep all have a very significant effect on the condition of hair, skin and nails.
Vitamin and mineral deficiencies
The most common vitamin and mineral deficiencies that can be observed in people experiencing excessive hair loss in women concern:
- biotin,
- iron and ferritin,
- zinc,
- selenium,
- silicon,
- vitamins B6, B12, B9 and D,
- sulphur amino acids.
Take care of your vitamins and minerals. Why? For example, biotin deficiency can lead to hair loss; without it, hair becomes thin, brittle and dull. It is key for the production of keratin, the main building block of hair. Lack of it may weaken hair bulbs and slow their growth. Iron, on the other hand, is important for the proper functioning of hair follicles. Without it, hair breaks, becomes weak and loses volume. It may enter the resting phase, and this leads to excessive shedding.
Diet, weight loss and calorie restrictions and hair condition
Too low a calorie intake quickly weakens hair, because it often does not provide an adequate amount of nutrients, vitamins and minerals. Low-protein diets are the most problematic – hair is keratin, which is a protein, so supplying it to the body is essential. Therefore, do not use restrictive diets and calorie limits, especially if you are in the process of losing weight. It is a good idea to consult your dietary decisions with a dietitian.
Scalp diseases and improper care
SD, i.e. seborrheic dermatitis, as well as AD, i.e. atopic dermatitis, in addition to dandruff or overuse of styling – all of this can intensify hair loss in women. If you have skin problems, be sure to see a dermatologist or trichologist. They will help you fight not only the symptoms, but also the cause of the scalp condition. If you can, also limit aggressive hair styling and use appropriate care – this will help hair stop becoming damaged and thinning.
Diagnostics, or before you reach for a supplement
Supplementation is a good choice to improve the condition of hair, but before you do it, you should first have tests done. Thanks to them, you will know which vitamin and mineral deficiencies you have, which you can easily replenish with supplements. Choosing blindly will not be as effective.
Which tests are worth doing for hair loss?
The basic blood tests worth doing for hair loss are:
- complete blood count,
- ferritin,
- TSH, fT3, fT4,
- vitamin D,
- vitamin B12,
- iron,
- cortisol (but in selected cases; it is worth consulting this with a doctor),
- sex hormones (only after consulting a doctor).
When are diet and supplements enough, and when is treatment necessary?
If hair loss results from excess stress, vitamin deficiencies and diet, supplementation and lifestyle changes may bring excellent results. Remember that putting together a healthy, nourishing and properly balanced diet, choosing the right supplements (matched to your vitamin and mineral deficiencies) and improving recovery and rest are the foundation, even if something more is going on. However, if the cause is thyroid disorders, anaemia or skin problems, treatment will be needed, and supplementation will be important support.
The role of diet and lifestyle in combating hair loss
A healthy lifestyle supports many truly positive effects, both for hair, skin and nails. Not only in women. It is important to skilfully select all nutrients in your diet, take care of sleep and limit stressful situations. We know that especially the latter may not be easy, but it is key and it is worth at least trying.
Which nutrients are key for strong hair?
Which vitamins are worth taking for hair? Which minerals are important for it? The most important components of a healthy diet for a woman, so that hair is strong and healthy, are: biotin, B vitamins, vitamins A, C, D and E, zinc, selenium, iron, silicon, sulphur amino acids (i.e. cysteine and methionine), omega-3 fatty acids and omega-6 fatty acids, as well as collagen.
Foods worth including in the diet
If you are wondering what to eat to have strong hair, make sure that your diet (if you do not have any food allergies or exclusions) includes products such as:
- eggs,
- fish,
- nuts,
- seeds,
- red meat (but in small amounts – as a source of iron),
- berries,
- olive oil,
- high-protein dairy products.
In the everyday rush, when it is difficult to properly balance your diet every day, the role of a comprehensive dietary supplement for hair becomes extremely valuable support.
Lifestyle: stress, sleep, stimulants and hair condition
Stress and lack of sleep are among the most common causes of weakened hair, especially in women. Hair reflects the lifestyle you lead – it is one of the first places where its effects can be seen. While we do not always have an influence on stress levels and sleep duration, giving up all stimulants will be incredibly important.
Supplements for hair loss – what should you pay attention to?
If you are looking for supplements that will improve the condition of your hair, do not be taken in by advertisements for products whose composition you do not know. Always read labels and check whether a given product, just like in our 7Nutrition store, provides the full composition, the content of individual ingredients and clearly described recommended dosage.
Hair tablets – do they really support?
Tablets for hair loss that are intended to improve its condition provide support, but only when they contain appropriate doses of key ingredients. Unfortunately, many products from hair tablet rankings that you will find on the Internet have doses that are too low to bring real effects. Therefore, be guided by the composition, not blindly by online rankings.
What ingredients should a hair supplement contain?
The best hair supplements contain, among other things:
- biotin,
- zinc,
- selenium,
- silicon,
- vitamins B6, B9, B12,
- vitamin D,
- collagen or sulphur amino acids,
- possibly iron.
The most common mistakes when choosing a supplement for hair loss
Pay attention to whether you are making these mistakes when looking for the best hair tablets! Do you buy something recommended on social media without reading the label and composition? Do you choose a product from an online ranking without finding out more about its manufacturer?
The most common problems when choosing a supplement are:
- too low a dose of active ingredients,
- lack of manufacturer transparency (a shell company or unknown origin),
- lack of standardised forms,
- “multitasking” supplements with microscopic concentrations of the given ingredients (for everything and... for nothing).

7Nutrition Marine Collagen supplement for hair loss in women
Why was this supplement created?
The 7Nutrition brand has for years been creating products of high purity and effectiveness, consulted with dietitians and specialists in supplementation and nutrition. In response to the growing needs of women, the Marine Collagen formula was created, based on natural collagen, which supports the growth of hair, skin and nails.
Composition of Marine Collagen 7Nutrition – what makes it stand out from others?
Discover the composition of our hair supplement, which was created with women in mind. It has more than one use, but if you are struggling with hair loss, you should definitely take an interest in it.
What does our collagen contain and why does it work?
- Hydrolysed Fish Collagen – this is the most absorbable form of collagen; it supports the hair growth phases, skin elasticity and resistance of hair follicles.
- Vitamin C – is essential for collagen synthesis and cell protection.
- Hyaluronic Acid – supports scalp hydration and prevents hair brittleness.
- Zinc – contributes to the maintenance of normal hair and normal skin.
- Biotin – contributes to the maintenance of normal hair.
- MSM, i.e. organic sulphur – improves hair structure.
In the composition of Marine Collagen, in one serving you will find the above active ingredients in the following doses:
- Collagen peptides from fish - 5000 mg,
- MSM - 500 mg,
- Acerola extract - 320 mg (including Vitamin C - 80 mg),
- Bamboo extract - 200 mg (including: Silica 150 mg, Silicon 70 mg),
- Sodium Hyaluronate - 50 mg,
- D-Biotin - 2,5 mg.
How does Marine Collagen 7Nutrition work?
Collagen from 7Nutrition supports the hair growth phases (so-called anagen), nourishes hair follicles, strengthens the hair structure and increases its resistance to damage. As a result, hair falls out less, while new hair grows faster and does not break. Moreover, it contributes to improving scalp hydration and condition and protects against oxidative stress.
Who is collagen intended for?
Collagen may be taken by women aged 25+ years, as well as after pregnancy or during the perimenopausal period (necessarily after consulting a doctor). Women who live under a lot of stress or after weight-loss diets should consider collagen supplementation. For people with thin, thinning, weakened hair, but who are not undergoing treatment that excludes supplementation, we encourage including the Marine Collagen collagen supplement in their diet.
How to use the supplement (dosage and duration of treatment)?
1 serving is recommended, i.e. 7 g of Marine Collagen preparation daily, preferably together with a meal (it would be great if it also contained protein). It should be dissolved in approx. 200 ml of water and consumed immediately after preparation. Do not exceed the recommended daily serving for consumption on your own. The minimum duration of treatment is 3 months, and the optimal one is 6 months, in line with the hair growth cycle.
Additional support in the form of Selenium from 7Nutrition
Selenium is one of the more important trace elements for hair growth. It contributes to the normal function of the immune system, the protection of cells from oxidative stress, normal thyroid function and scalp health. Before supplementation, it is worth testing the level of selenium in the body. If there are no contraindications to using selenium, it will work very well as an addition to Marine Collagen for women who want to improve the appearance of their hair.
Safety of use and contraindications
Supplements should always be stored out of reach of children. Their use is not recommended for pregnant women, breastfeeding women, children or people allergic to any of the ingredients. It is also worth remembering that a dietary supplement is never a substitute for a varied diet. A balanced diet and a healthy lifestyle are important for proper health.
Effects of use – when can you expect improvement?
Most women who are looking for quick ways to improve the appearance of their hair, skin and nails hope that the effects will come quickly. But the truth is that you have to wait a while for them and be patient. Regular supplementation is the key to achieving the expected results.
How long does it take for hair supplements to work?
The first effects of hair supplements are visible after just 3-6 weeks. They appear in the form of so-called baby hair, and it also begins to be visible that a little less hair is falling out. A full assessment of the effect of supplementation against hair loss can take place only after approx. 3-6 months, in line with the anagen cycle.
How to assess the effects? Not only by the amount of hair on the brush
It is best to take “before” and “after” photos, observe the hairline and the overall condition of the scalp. It is also worth paying attention to whether hair brittleness is decreasing. Ultimately, the amount of hair that falls out (visible on the brush or in the shower or bathtub drain) should be visibly lower to the naked eye. However, remember that every hair must fall out, so you will not eliminate this completely, because it is a natural process of the hair life cycle.
A comprehensive approach, i.e. supplement + care + lifestyle
How to stop hair loss? We probably will not surprise you by saying that to achieve the best possible results, you need to take care of yourself comprehensively. Supplementation alone is not enough. If you want lasting effects, you need to change your existing unhealthy habits and take care of other aspects of health.
Why is a supplement alone not enough?
A comprehensive hair treatment is essential. Why? Hair reacts to everything: stress, diet, hormones, sleep. A supplement is the foundation, but it must go hand in hand with lifestyle. Therefore, follow a healthy, balanced diet, make sure you get at least 7-8 hours of sleep each day and try to reduce stress whenever possible. Add to this appropriate supplementation from 7Nutrition and hair care.
Scalp care for hair loss
How to care for hair when it is falling out? Regularly use gentle shampoos, perform a gentle scalp massage and trichological peels. As far as possible, avoid heat styling your hair, and if you must do it, apply products with UV protection to your hair.
Habits that support the action of supplements
It is good to build good habits that support health and, in addition, make it easier for supplements such as collagen and selenium to act properly on hair. This is very important. Why? Because if you use supplementation against hair loss and then do not take care of diet and sleep, it is a bit like building a tower of blocks and each time taking a block from the very bottom. The tower will collapse, and you will keep being forced to build it from scratch. The effects? Rather poor, right? That is why getting enough sleep, reducing stress, and a diet rich in protein and healthy fats are so important. By taking care of the basics, you will give your body a solid foundation for regeneration and absorption of beneficial ingredients from supplements.
