What is deep conditioning?
“Deep Conditioning” is often suggested as a remedy for dry or damaged hair. The goal of deep conditioning is to strengthen damaged hair and prevent breakage. To deep condition you must use a conditioner that contains ingredients that can absorb into the hair strand. Examples of penetrating ingredients include hydrolyzed protein, amino acids, cetrimonium bromide, panthenol and some silicones.
Does deep conditioning require heat?
No, it’s a common myth that deep conditioning requires heat. If a conditioner works with heat, its instructions will tell you to apply heat for a specific amount of time. Heat will only increase the effect of a conditioner if it has been formulated with penetrating ingredients. Conditioners that require heat don’t work better than conditioners that tell you to apply and rinse after a few minutes. It all depends on the ingredients.
