Proteins play a role in virtually every biological process including hair. Keratin, which hair is made of, is a strong protein that can break down with sun exposure, wind, cold weather, pollutants, daily maintenance, manipulation, heat tools, and chemical treatments like permanent color. This is where using protein treatments come in to help temporarily repair the hair strands. Protein treatments are used to add STRENGTH and RESILIENCE to damaged hair by attaching hydrolyzed proteins directly to the hair follicle and hardening the cuticle layer. If there are holes in the hair cuticle, it will fill those holes or gaps while also placing a barrier around the hair shaft to lessen further damage. Most protein treatments are conditioning treatments. They can be a deep conditioner, light, or reconstructor (heavy). There are different products that you can use but in Zambia the most common are those in the picture and you can find them in chemists and supermarkets.
