Healthy or dry hair ultimately comes down to how much moisture it contains. Elasticity, shine and manageability are all affected. When your hair is dried out in sun, salt water, chlorine, heat styling tools or when humidity is low, water evaporates from the hair. This results in the hair becoming rough and dull. It's important to use products that add protection and moisture back into the hair, returning softness and shine. Damaged hair lacks shine and vitality. The hair is often damaged from the inside which can lead to breakage and split ends. Home coloring, bleaching or perming treatments can damage the inner portion of the hair. The outer layer will lose its shine and become difficult to brush and manage. Tears and breakage appear in the hair which can become porous, losing its elasticity and causing breakage. Products for dry and damaged hair will help to restore the protein damage and deeply hydrate. Use thermal protectors when styling and try to deep condition at least once a week.
