Overview
Women noticing thinning or postpartum shedding get a sulfate-free shampoo packed with rosemary oil, caffeine and biotin for the roots, plus zinc, probiotics and saw palmetto for scalp balance.
A broad botanical blend targets scalp health and strand strength in one daily wash. It is safe for color-treated hair. Thinning with a medical cause needs professional advice, and visible change takes consistent use.
Who it's for
Women with fine, brittle or shedding hair, including after pregnancy, will find a gentle routine step. Anyone with sudden or severe hair loss should consult a doctor.

Performance notes
Rosemary oil and caffeine are included to stimulate the scalp, while biotin strengthens fine strands against breakage. Zinc and probiotics support scalp balance and help reduce flakes. Castor and argan oils add shine as hair is washed.
