Key takeaways
- Strong hair is hair whose fibre and cuticle are preserved.
- Fragility mainly comes from heat, colouring, brushing and dryness.
- Hair is strengthened by protecting and nourishing the fibre, both externally and internally.
- Key active ingredients: horsetail, nettle.
- Zinc and vitamin B8 contribute to the maintenance of normal hair.
What is strong hair?
“Strong” hair is not magically thicker: it is hair whose keratin fibre and protective cuticle are intact. It is therefore more resistant to handling, breaks less and retains its length. Strengthening means, above all, preserving and supporting this structure.
Why is my hair fragile?
- Repeated heat (hairdryer, straighteners, curling iron).
- Colouring and bleaching, which weaken the structure.
- Harsh brushing, especially on wet hair.
- Dryness, which makes the fibre brittle.
- A diet low in protein and micronutrients.
How can you strengthen your hair every day?
- Reduce heat and apply a heat protectant.
- Nourish the fibre regularly (mask, treatment on the lengths).
- Detangle gently, from the ends towards the roots.
- Space out colouring treatments and tight hairstyles.
- Support the fibre from within with a 3-month programme.
