Hair loss and hair breakage are frustrating problems for many people. You notice more hairs in your brush, on your clothes, or in the shower drain and wonder: is it stress, seasonal changes, heat styling tools, or the wrong hair care? That’s why the Kérastase Genesis range has become incredibly popular in recent years. But the question remains: does Kérastase Genesis really work against hair loss?
In this blog, we explain exactly what Genesis does, who the range is suitable for, and why so many people notice a difference after using it consistently.
Hair loss or hair breakage: what’s the difference?
Many people talk about hair loss when what they are actually experiencing is hair breakage. That difference is important.
Hair loss
With true hair loss, the hair falls out from the root. This can have several causes:
- stress
- hormonal changes
- nutritional deficiencies
- pregnancy
- hereditary factors
- fatigue
Hair breakage
With hair breakage occurs when weakened hair snaps. This often happens because of:
- heat from styling tools
- bleaching or dyeing
- wearing the hair tightly pulled back
- brushing
- dryness and damage
The Kérastase Genesis range focuses primarily on reducing hair loss caused by breakage and strengthening fragile hair.
What exactly is Kérastase Genesis?
Genesis is designed for weakened hair that is prone to falling out due to breakage. The range combines scalp care with strengthening the hair fiber. This not only makes the hair feel stronger, but often also look fuller and healthier.
