What weakens your hair lengths
Help, I have dry ends and damaged lengths. How did this happen?
Using too much heat on your hair, harsh dyes, straightening it too often, UV rays, wind, lack of proper treatments...
1. The hydrolipidic film, the hair's protective barrier is affected: exposed to various aggressions, this protective surface shield no longer fully plays its role as a barrier. The already weakened hair is exposed to external aggression.
2. The cuticle lifts up: when the scales that form the cuticle are damages and become detached, the inside of the hair is exposed, the water naturally present in the hair evaporates excessively and the hair dries out.
3. Keratin damage at the heart of the hair: Damaged by these micro-traumas, the keratin chains that make up the hair break up. When this is lacking, the hair becomes porous, brittle, dry and less beautiful.
What does hair need to grow?
Hair growth up close...
For its growth, the hair relies on the contribution of numerous active ingredients:
- Sulphur amino acids, methionine, cysteine and cystine, which are necessary for the synthesis of keratin
-Fatty acids (linoleic acid, linolenic acid, arachidonic acid), which are necessary for the inter-cellular cement that holds the cells together
- Metals and vitamins (zinc, copper, vitamins A, C, B5, B6, B8) which are necessary for many reactions in the body, and in particular for the synthesis of hair constituents.
All these elements are brought to the follicle by the vascular network (blood vessels). The vascularisation of the follicular papilla therefore plays a fundamental role in the supply of nutrients to the hair bulb cells. Hormones also play an important role in the secretion of sebum.
