Hormonal Hair Loss in Women
Ingredients Help Hormonal Hair Loss
Biotin
Shampoos containing biotin help strengthening hair strands by supporting keratin production. Keratin is the protein that forms hair, and this improves the structure and resilience of each hair.
According to a 2017 review published in Skin Appendage Disorders by Deepa P. Patel, Shane M. Swink, and Leslie Castelo-soccio, biotin was found to help only in cases where an underlying deficiency or medical condition is present.
Caffeine
Caffeine stimulates hair follicles by increasing blood circulation to the scalp, which improves the delivery of oxygen and nutrients. It slightly widens blood vessels, improving blood flow.
This may encourage stronger hair growth and reduce shedding. Caffene-based shampoos can also help counter DHT's effects, supporting thicker and healther-looking strands.
Scientifically, Fischer et al. demonstrated that caffeine penetrates follicles within 2 mins and stimulates hair shaft elongation.
Amino Acids/ Keratin
Amino acids are the building blocks of keratin, and keratin is the actual protein that makes up hair. They help rebuild damaged hair by reinforcing the internal structure of each strand. Keratin fills gaps caused by heat, colouring, or breakage, while amino acids rebuild the inner protein bonds. They also improve elasticity, which helps hair stretch without snapping.
Your hair can instantly look fuller after using a keratin shampoo or treatment because it coats the hair shaft and fills in gaps, making each strand appear thicker, stronger, and more voluminous.
Studies in 2018 titled "Effect of Amino Acid-Based Treatments on Hair Elasticity" by S. Nakamura et al., published in the Journal of Oleo Science, found that amino acid complexes improve hair elasticity, hydration, and flexibility, making hair resilient and less prone to breakage.
Niacinamide
Niacinamide is getting a lot of hype these days because it helps strengthen the scalp barrier by improving moisture retention, reducing inflammation, and supporting healthier follicle function. It creates a more balanced scalp environment, encourages stronger and healthier hair growth.It also gently boosts nutrient delivery to follicles.
Naicinamide works well for both oily and dry scalps. It helps hydrate a dry scalp while also regulating excess sebum on an oily scalp.
A 2017 study in the International Journal of Trichology by T. Tosti et al. reported that niacinamide improves keratin quality and enhances hair fullness, making strands appear thicker and healthier.
DHT-Blocking Botanicals
DHT (dihydrotestosterone) is a by-product of testosterone which can shrink hair follicles. DHT-Blocking botanicals help reduce hormonal shedding in women experiencing PCOS or hormonal imbalance caused by puberty, perimenopause or menopause.
They reduce DHT activity by limiting how strongly DHT binds to the follicles. This helps the follicles stay stronger, and less prone to shrinking, and healthier follicles shed less - resulting in fuller-looking hair.
Scientific reviews from 2024 and 2006 show that several botanicals including saw palmetto, pumpkin seed oil, green tea, stinging nettle, and rosemary can inhibit five-alpha-reductase, helping reduce DHT levels and supporting hair density in androgen-related hair loss. They are also among the strongest natural DHT Blockers.
Low-Sulphate Formulae
Commercial shampoos include sulphates, which can increase frizz and weaken the cuticle. Low-Sulphate formulae help prevent further breakage by cleansing the hair gently without stripping away natural oils. By protecting the hair's natural moisture balance, they keep strands less prone to damage. Look for sulphate-free or low-sulphate shampoos if you have dry or brittle hair.
They are also recommended for chemically treated, heat-damaged, or hormonally thinning hair. Women with curly or wavy hair often prefer sulphate-free shampoos because they help maintain softness and reduce frizz.
A 2014 study published in the Journal of Dermatolgy states that sulphates can trigger irritation, redness, and disrupt scalp barrier.
Best Shampoo for Hormonal Hair Loss in Women
1. Alpecin C1 Caffeine Shampoo
2. Pharmaceris H Keratineum
Hormonal hair loss in women (PCOS, postpartum, perimenopause, menopause) is often linked to DHT sensitivity, weakened roots, and reduced keratin quality. This shampoo is best for women experiencing poor hair keratin quality and increased hair breakage.
Pharmaceris H is a budget-friendly option but uses dermatology-grade ingredients to support scalp nourishment and hair strengthening. It contains caffeine, which energises weakened hair roots; biotin, which improves keratin structure; panthenol for hydration, and low-sulphate surfactants that help prevent cuticle damage.
Most hormonal hair loss shampoos only target DHT or circulation, but Pharmaceris adds keratin, biotin, pathenol, which makes it stand out.
3. Nanogen Thickening Shampoo
Nanogen thickening shampoo gives instant thickness and has a gentle, sulphate-free formula for fine and thin hair. It contains amino acids/keratin, niacinamide, and a small amount of caffeine. It offers partial DHT-Blocking support and is sulphate-free, making it ideal for early-stage thinning.
Nanogen is widely recognised because it delivers instant cosmetic thickness. It's not a hormonal hair-loss treatment, instead, it's a cosmetic thickening and strengthening shampoo. Aloe and chamomile help calm irritation and supoort sensitive scalps.
4. Plantur 39 Phyto-Caffeine Shampoo
Plantur 39 is specifically formulated for women over 40 experiencing menopausal or perimenopausal hair thinning. It's ideal for women with fine, brittle, colour-damaged hair, or for those whose hair becomes weaker due to declining estrogen levels.
This brand states that it's designed for menopausal hair loss, where estrogen drops and testosterone sensitivity increases. Anyone experiencing hormone-related thinning can use it, especially when the roots feel weakened.
Plantur 39 is one of the first shampoos scientifically developed for menopausal hair loss, and its phyto-caffeine complex has clinical evidence showing reduced hair shedding after 3-4 months of use.
The key functional ingredients include caffeine, niacinamide, zinc PCA, panthenol (Pro-Vitamin B5), and hydrolysed wheat protein. These are designed to activate hair roots, strengthen resilience, and repair damaged hair. Pathenol hydrates the hair fibre, while wheat protein restores strength to dry, damaged hair.
* In women, if hair loss is rapid, patchy, or long term, it's best to book an appointment with the GP as it can be caused by thyroid issues, iron deficiency, or hormonal imbalance.
