Lazartigue Stronger Hair Serum
Anti-Hair Loss, Strengthening, and Scalp Care
The Lazartigue Stronger Hair Serum is formulated to combat reactive hair loss, strengthen hair fibres, and create the ideal scalp environment for healthy growth. This vegan, alcohol-free serum contains 97% ingredients of natural origin, including powerful active complexes Capixyl™ and Neutrazen™, designed to slow hair loss, densify weakened hair, and soothe the scalp. Over time, hair becomes stronger, denser, and more resilient.
What Is Lazartigue Stronger Hair Serum?
The Stronger Hair Serum is a concentrated botanical treatment targeting sudden hair loss. Unlike temporary fixes, it works at the root level by:
- Strengthening the anchorage of existing hair in the follicle
- Promoting the growth of weakened hair
- Supporting scalp health and balance
- Reducing susceptibility to external aggressions
Its lightweight gel texture ensures that it absorbs quickly, leaving a non-greasy finish, making it suitable for daily use on dry or slightly damp scalp.
Who Is It For?
This serum is recommended for:
- Individuals experiencing sudden or reactive hair loss
- Hair that feels fragile, thin, or weak
- Scalp prone to sensitivity or irritation
- Anyone seeking a natural, alcohol-free solution to strengthen and densify hair
- People looking to boost hair vitality at seasonal changes
It is ideal for anyone wanting to slow hair shedding, promote healthier hair growth, and maintain scalp balance.
How Does Lazartigue Stronger Serum Work?
The serum works through a dual-action formula:
Boost Hair Growth and Strengthen the Fibre
Capixyl™ (2.5%): Derived from red clover, this active complex combines Biochanin A and Acetyl Tetrapeptide-3 to strengthen hair anchorage in the follicle, slow hair loss, and densify hair. It creates the perfect environment for weakened hair to regrow thicker and stronger.
Soothe and Protect the Scalp
Neutrazen™ (1%): A biomimetic peptide that calms hypersensitive scalps, maintains scalp balance, and improves hair resistance to external aggressions.
Clinical results after 2 months of daily use:
- 89%: Sudden hair loss slowed
- 89%: Hair more resistant
Use test on 19 volunteers, 1 application/day for 2 months.
Key Benefits
- Slows sudden hair loss by strengthening hair anchorage
- Promotes growth of existing hair, making it thicker and denser
- Soothes scalp sensitivity to create a healthier growth environment
- Alcohol-free formula: avoids disrupting the scalp’s hydrolipidic film
- Vegan, silicone-free, and mineral oil-free
- Lightweight, non-greasy gel that absorbs quickly
This serum supports hair from the roots, providing visible improvements in hair strength and density over time.
