My tips are extremely damaged - fine hair, color, etc .. Straightener - Hair stylist therefore no gradients can really help me :( Solution: short cut. Finally, I cut as much as possible + - 2 cm (but there are still far too) + castor oil every week + thermo -protecteur Kerastase. Already 3 weeks of treatment and I am already satisfied with the result! My horrible spikes are much less visible. My hair is a little weighed down on the day of the application only. I strongly recommend this product to hide split ends. I hope that this will prevent my new forked spikes.
