Hair Diagnosis:

Throughout life, hair falls out and is renewed. Normal hair loss is about 100 hairs per day. More, and the loss is abnormal and must be due to a disruption in the hair cycle. If you experience sudden and massive hair loss following a specific event such as a period of stress, pregnancy, illness or a change of season, the loss is said to be reactive. You then see more hair on the pillow, in the shower or on the brush when styling... This type of hair loss is due to a sudden deficiency in the scalp's blood microcirculation and nutrient supply.

Sudden hair loss is not permanent, but it should be remedied quickly in order to slow down hair loss and to avoid permanently weakening the hair. 

Why we love it: 

This serum directly targets sudden hair loss with a powerful blend of two active ingredients that help slow down hair loss while creating the right environment for hair growth. 

1/ Boosts the growth of existing hair:

Present at a level of 2.5%, Capixyl^TM, derived from red clover, helps to create a good growth environment for the hair follicle and to promote the growth of weakened hair. The hair is thus better anchored in the follicle and grows thicker. It also encourages growth and increases resistance of healthy hair.

2/ Soothes and protects the scalp:

Neutrazen^TM (1%) is an active ingredient of natural origin with soothing properties that helps combat scalp hypersensitivity. It helps maintain the balance of the scalp to tone it

How to use:

In combination with Fortify fortifying shampoo, anti-hair loss complement and Boost hair supplement, apply 4 pipettes* daily for 3 months to the entire dry or slightly damp scalp:

• Divide the scalp into four areas.
• For each area, fill the pipette and gradually apply the serum by moving the pipette along the area.
• Massage in to promote microcirculation and energise the scalp.
• Do not rinse. Allow the area to dry. 

*Depending on your hair density, you can apply up to 6 pipettes

BENEFITS

Its vegan formula is alcohol-free

The alcohol has an astringent power that allows it to instantly tighten the pores of the scalp. This effect is temporary and short-lived. But alcohol can also alter the hydrolipidic film of the scalp and make it more vulnerable. As a result, it may be more susceptible to irritation, which is not conducive to hair growth.

The Stronger serum, formulated without alcohol, helps to create a favourable environment for healthy hair growth.

Lazartigue Stronger serum is vegan, alcohol-free, silicone-free and mineral oil-free. It contains 97% ingredients of natural origin.

Its made in France formula contains CAPIXYL^TM and NEUTRAZEN^TM, two powerful associations of active ingredients of natural origin which act in a complementary way to slow down sudden hair loss. 

2.5% CAPIXYL^TM:

• Biochanin A: this naturally occurring molecule, extracted from red clover, helps to combat thinning hair and strengthen its anchorage in the scalp. Hair loss is thereby slowed down.
• Acetyl tetrapeptide-3: this unique combination of peptides helps strengthen and densify hair. As a result, its grows thicker and stronger, and the hair looks denser. 

• 1% Neutrazen^TM: thanks to its soothing action, this biomimetic peptide tones the scalp by helping to preserve its balance. The scalp is soothed and the hair is more resistant to external aggressions.
