How Does Hair Growth Work?
The hair growth cycle is a continuous loop involving 4 distinct phases:1. Anagen (Growth Phase): This is the active growth phase that lasts 3 to 4 years. About 85% to 90% of your hair is typically in this phase. In cases of hair loss, this growth period may become significantly shorter.
2. Catagen (Transition Phase): A brief 2 to 3-week phase where hair growth stops, and the hair follicle gradually shrinks.
3. Telogen (Resting Phase): This is the pause phase, lasting around 3 months before the hair falls out. Normally, about 10% to 15% of your hair is in this resting phase. For those experiencing hair loss, a higher percentage of hair may remain in this phase, resulting in visibly thinner hair.
4. Exogen (Shedding Phase): This is the phase where the hair naturally falls out, typically lasting 2 to 6 months. It is completely normal to shed some hair daily.
How to increase hair density?
Our Innovative Solutions Density Booster Anti-Fall Routine
The key to reducing visible hair loss and boosting hair density does not lie in a single gesture but in the consistency of a complete hair care routine. The Density Booster Collection provides a 3-step regimen designed to act on both the scalp and the hair fiber at every level, resulting in up to 10x less hair loss due to breakage.

1. Density Booster Shampoo
The Density Booster Anti-Fall Shampoo is designed for regular use to optimize results. Its sulfate-free formula gently cleanses while stimulating microcirculation with the combined action of Aminexil, Niacinamide, and Ginger Root Extract. It prepares the scalp to receive the following hair treatments, while minimizing external stressors that weaken the hair fiber.
2. Density Booster Conditioner
Enriched with 5% Aminexil and formulated without silicones, the Density Booster Conditioner acts on lengths and ends, where breakage is most common. It coats the hair strands, strengthens resilience, and reduces breakage. It is used as a classic conditioner, with a short application time before rinsing.
3. Density Booster Anti-Fall Serum
The Density Booster Hair Serum is the most concentrated hair care product in the range, containing 8% Aminexil. It is applied directly to the scalp 5 to 7 times per week, without rinsing. Its purpose: to extend the hair's life cycle, strengthen its anchorage, and limit visible hair loss. Its lightweight texture allows for easy application without a greasy effect.

Aminexil-R: Density Booster's hero ingredient
Aminexil-R is the core component of the Density Booster formula, designed to strengthen the hair fiber and prolong its life cycle. This patented ingredient by L'Oréal Paris is specifically formulated to combat hair weakening and maintain hair density.
Aminexil-R works by softening the collagen layer around the hair follicle. Over time, this collagen can harden, forming a barrier that prevents the hair from anchoring properly to the scalp. This process accelerates premature hair loss and weakens hair density. Aminexil-R helps to soften this collagen barrier, allowing hair to stay rooted longer and complete its natural growth cycle. The result: reduced breakage and visibly denser hair.
