A daily scalp serum for sudden, seasonal or stress-related hair fall
Lazartigue Stronger Reactional Anti-Hair Loss Serum is a vegan scalp serum for seasonal or reactional hair fall, the sudden shedding that can follow stress, fatigue, pregnancy or a change of season. It combines two botanical complexes: Capixyl™, red clover peptides that help keep hair anchored and support stronger growth, and Neutrazen™, a soothing tripeptide that calms a sensitive scalp. Over three months, hair fall slows and the hair looks stronger and fuller.
How it works
A light gel serum with a dropper that does not grease the hair and has a fresh minty scent.
Who it suits
- Sudden or seasonal hair fall
- Shedding after stress, fatigue or pregnancy
- Sensitive or itchy scalps
Worth knowing before you buy: a 3-month course is needed to see a difference. It reduces hair fall and helps hair look fuller, but it is not a treatment for hereditary thinning.
How long one bottle lasts
At 4 to 6 drops a day, the 50ml bottle covers about one month, so plan three for a full course.
