Collagen is essential for young-looking skin, and also proves to be a major ally in your quest for perfect locks. Here is ample proof of its little-known benefits for your hair.

1. It hydrates your hair

Collagen molecules, which are naturally present in the body, have hydrating and reparative properties which also make them miracle workers for the hair fibre as well as the skin, like hyaluronic acid. They add water, trapping it in the core of the hair fibre so that you can say goodbye to dehydrated course locks. That’s why they are an essential part of the formula for Jean Louis David’s Hydration & Suppleness shampoo from the Hydra Therapy range!

2. It acts as a real shield for weakened locks!

By filling gaps in the hair fibre in the same way as it fills wrinkles, collagen strengthens your hair long term. The proteins that it releases gradually coat the hair’s cuticles and encase them to form a protective film on the hair’s surface.

3. It boosts your hair’s volume

By penetrating the fibre, collagen increases each individual hair’s diameter for visibly thicker locks. A real godsend for those with fine hair who wish to get maximum volume or those with sparse locks who will immediately notice that their hair seems thicker.

4. It’s the key to (almost) permanently perfect blow-drying

This is a dream for many and yet a feat made possible by nothing more than collagen straightening. This will make your locks more supple to give them a beautiful, very natural blow-dried look which will last for up to six months!
