Kerastase Specifique Anti Thinning Treatment 42x6ml is an intensive 42-day anti-hair loss program for thinning hair, formulated with Aminexil 15,000 PPM, Rhamnose, and Complexe AOX. This leave-in vial treatment helps reduce the rate of hair loss, strengthens the hair root, and improves the appearance of density, leaving hair looking thicker, stronger, and more resilient over the course of the cure.

Why This Anti-Thinning Treatment Works

Hair thinning is often linked to the premature aging of the hair follicle and a shortened hair life cycle, which can be triggered by factors such as stress, hormonal changes, and seasonal shifts. This Kerastase anti-thinning treatment targets the scalp at the root, working over a structured 42-day course to help anchor hair more firmly and protect the follicle from oxidative stress. In a clinical test on 119 of 130 people versus a placebo, results were seen with daily application over six weeks. The lightweight, leave-in formula absorbs quickly without leaving roots greasy, so it fits easily into a daily routine and lets you style your hair as usual afterwards.

Who It's For

This intensive cure is ideal for men and women noticing thinning hair, increased shedding while brushing, washing, or sleeping, or a loss of volume at the roots. It is designed as a leave-in scalp treatment rather than a shampoo, and works best alongside a Specifique anti-thinning shampoo as part of a complete scalp routine. Because it is an intensive 42-vial program, consistency over the full course matters most for visible results. For ongoing or severe hair loss, or if you are pregnant or nursing, consult a healthcare provider or dermatologist before starting any new treatment.

• Aminexil 15,000 PPM: A blend of Aminexil, GlucoLipide GL, and Madecassoside that helps improve the health of tissues around the hair root, making them more flexible so the root anchors more firmly into the scalp.

• Rhamnose: A vegetable sugar with anti-aging properties that supports the production of collagen and elastin for scalp suppleness and flexibility.

• Complexe AOX: An antioxidant complex that helps protect the scalp and hair from the effects of oxidative stress.

1. Apply one vial daily to a dry or towel-dried scalp.

2. Distribute section by section and massage gently with fingertips to aid absorption.
