Use good name brand products, Jane Carter Solution, Mixed-Chicks, Pantene or Keracare are highly recommended. Use a good (leave-in) conditioner to keep your hair soft. Dont over do it. Too much conditioner or any other hair care product can cause a build up and tangling. Avoid hair products that contain alcohol. Alcohol makes hair dry. Ask your stylist what would be the best products for your hair. Chemical agents are widely used to add curl to straight hair and to loosen curls in curly hair. These products defat the scalp and permanently alter the structure of the hair. These compounds can also cause severe hair loss from over processing. Never use perms or relaxers on damaged hair. If possible, allow the hair to regrow before introducing new chemical processes.
