However, be very gentle with your hair when it is wet, as it is most fragile then. This type of conditioner will hydrate your hair and help it to be less frizzy, as its purpose is to also smooth your cuticles and add softness. (Think of when you add softener to your clothes after washing them.) A leave-in conditioner, on the other hand, locks the moisture in the hair strands for a longer period than a conditioner you rinse out. You might want to use this type of conditioner when you get your hair wet and after you shampoo. The role of these conditioners is to refortify the cuticle with a protective coating and add additional moisture to the cortex, allowing the hair to keep growing without breaking. A leave-in conditioner is to be used after washing your hair to replenish and maintain moisture. They are not rinsed out and are useful for controlling frizz, detangling strands, and keeping curls smooth. These conditioners are normally light lotions, creams, or liquids. Leave-in sprays are also effective; they are easy to apply to the ends of hair that need special attention and protection for retaining length. Other things that affect the protein structure of the hair include: These conditioners are normally quite thick in consistency and should be left on the hair, with heat, for 20 to 30 minutes. Think of deep conditioners as a five-star meal for your hair. Specifically, this type of treatment has significant benefits to the overall health and well-being of Afro-textured hair. Deep treatments can be used weekly or every two weeks depending on the current health status of your hair and individual needs. Of course, you will need to take into account your hair’s characteristics, such as texture (fine, medium, or thick strands), your porosity, elasticity, and the strength of your hair. All of this will help you think about the products and possible changes in styling your hair that best support its health needs. Adapted from You and Your Hair by Sarah Roberts.
