Good day,
It sounds like you are suffering from a dryness issue.
I would recommend the Moroccan Oil Restorative Hair Mask or the Intense Hydrating Mask along with the Moisture Repair Shampoo and Conditioner. If you have a bigger budget then you can try the Kerastase Masqueintense along with the Bain Satin 2 Shampoo and the Fondant Nutri-Thermique Conditioner.
Thank you!
