The Breton manufacturer Lessonia presents Alter-Thickhair, a plant-based ingredient designed to densify hair. Made from fibers derived from oud wood, this new product is a natural, sustainable and vegan alternative to traditional fibers such as nylon, cotton or keratin.
Meeting the expectations of a changing market
Faced with the problems of hair density loss linked to stress, hormonal variations or diet, demand for natural, effective solutions is growing. At the same time, formulations are increasingly oriented towards responsible ingredients, without compromising performance.
This is the background to Alter-Thickhair, designed to meet both the environmental challenges and the efficiency needs of hair care brands.
A reused raw material: oud wood
Traditionally used in perfumery, oud wood reveals a new use here. Lessonia uses the residues from the distillation of its essential oil to create an upcycled hair fiber, through a grinding and micronization process carried out at its Saint-Thonan plant in Brittany.
Natural electrostatic fixation
The resulting fibers have a positive charge that interacts with the hair's naturally negative charge. This electrostatic adhesion mechanism ensures even distribution, long-lasting hold without residue or transfer, and a natural look.
An ingredient that can be adapted to your needs
Available in two standard shades (Natural and Brown), Alter-Thickhair can be customized to meet the requirements of formulators and brands.

«With Alter-Thickhair, we give a second life to a precious and rare raw material used in perfumery. It's an innovation that combines durability and visible effectiveness. The effect is incredible as soon as you apply it, explains Marion Lagadec, Lessonia's Marketing Manager.
