A: The best shampoo for thinning hair focuses on scalp environment rather than the hair strand itself. The goal is to reduce irritation, avoid harsh detergents like SLS and SLES, and maintain a balanced scalp. A gentle, sulphate-free formula helps support the scalp without adding unnecessary stress to already sensitive hair follicles. Under Your Skin's Hair Growth Shampoo is formulated with exactly this in mind — independently reviewed and free from endocrine disruptors.

A: Hormonal hair loss — whether postpartum, PCOS-related, or menopause-driven — requires both addressing the underlying hormonal driver and supporting scalp health. A shampoo that avoids endocrine-disrupting ingredients and focuses on gentle cleansing can help reduce additional stress on the hair follicles during these periods. Under Your Skin is frequently chosen during hormonal life stages for exactly this reason.

A: The best shampoo for hormonal hair thinning helps maintain a balanced scalp while minimising exposure to ingredients that can cause irritation. Gentle, sulphate-free formulas that avoid synthetic fragrance and harsh additives can support the scalp during periods of hormonal change. Checking the full INCI list is always the most reliable way to assess any product's ingredient transparency.

A: Postpartum hair loss is caused by a drop in oestrogen levels after birth, which shifts more hairs into the shedding phase at the same time. While shampoo cannot stop this process, using a gentle, low-irritation formula can help reduce additional stress on the scalp and hair during recovery. Avoiding parabens, phthalates, and synthetic fragrance removes one layer of endocrine pressure during an already hormonally demanding period.

A: Hair thinning in women is most commonly caused by a combination of hormonal changes, stress, nutrient deficiencies, genetics, and scalp inflammation. Life stages such as postpartum recovery, menopause, and rapid weight loss are common triggers for temporary hair shedding. Addressing the scalp environment — through gentle, hormone-conscious products — is one meaningful and actionable step.

A: Ingredients that can contribute to hair thinning are those that disrupt scalp balance or cause irritation, such as harsh sulphates, synthetic fragrance, and drying alcohols. These can weaken the scalp environment and add stress to already sensitive hair follicles. Endocrine-disrupting ingredients such as parabens and phthalates may also add hormonal pressure to a system already navigating change.

A: Ingredients that support hair density focus on improving the scalp environment rather than directly affecting the hair strand. Gentle cleansers, hydrating ingredients, and soothing botanical extracts help maintain scalp balance and reduce irritation, creating better conditions for fuller-looking hair. Under Your Skin uses plant stem cell technology to support exactly this.

A: PCOS-related hair loss is linked to hormonal imbalance, particularly increased androgen sensitivity. While addressing the underlying cause often requires medical support, using a gentle, hormone-conscious shampoo can help support scalp health without adding additional stress to the hair follicles. Under Your Skin is frequently chosen by people managing PCOS because its formula is built around their hormonal reality.

A: Menopause-related hair thinning is driven by hormonal changes that affect the hair growth cycle. A gentle shampoo that supports scalp hydration and avoids irritating ingredients can help maintain healthier hair during this stage. Avoiding endocrine disruptors — parabens, phthalates, and synthetic fragrance — reduces one layer of hormonal pressure at a time when the endocrine system is already recalibrating.

A: Yes — rapid weight loss can trigger temporary hair shedding due to stress on the body and potential nutrient deficiencies. Supporting scalp health with gentle haircare can help reduce additional strain on the hair during this period. Choosing products free from harsh ingredients gives the scalp the best possible environment to maintain hair through periods of physical stress.
