This shampoo is formulated specifically for women dealing with hair thinning — Phyto markets it for hereditary, age-related or menopause-related thinning rather than as a unisex or general-purpose product, unlike some other shampoos in the Phyto lineup.

It's designed to be used as the cleansing first step of a Phytocyane regimen alongside the separate leave-in Phytocyane serum, so it suits someone building a full thinning-hair routine as much as someone who wants a gentle, treatment-adjacent shampoo.

Phytocyane's shampoo earns its place in a thinning-hair routine less as a stand-alone treatment and more as scalp prep — ginkgo biloba and grape seed extract are there to support the scalp environment before the leave-in Phytocyane serum does the heavier lifting, and the formula is specifically tuned to hormonal and age-related thinning patterns in women rather than general hair weakness.

1. Wet the scalp thoroughly.
2. Apply the shampoo and massage in a circular motion.
3. Rinse.
4. For treatment use, apply a second time and leave on the scalp for 2 minutes before rinsing.
5. Avoid contact with eyes; rinse with water if contact occurs.

Pros

• Formulated specifically for women's hair thinning rather than as a generic strengthening shampoo, matching the hormonal and age-related thinning patterns Phyto designed it around.
• Contains ginkgo biloba and grape seed extract, both included as antioxidant, circulation-supporting actives rather than filler botanicals.
• Designed to integrate with the separate Phytocyane leave-in serum for a complete regimen.

Cons

• Contains sodium laureth sulfate, so despite being a 'treatment' shampoo it is not sulfate-free.
• Fragrance ingredients include citral and limonene, both recognized fragrance allergens, worth knowing for a sensitive or already-irritated scalp.
• On its own, without the companion Phytocyane serum, it functions mainly as a scalp-preparing cleanser rather than the core active treatment for hair thinning.
