Keep your hair moisturized daily. The biggest concern after relaxing is often the level of dryness in your hair. You will need to take steps to add extra moisture to your hair to prevent frizziness and breakage.
Take care of your scalp. Scalps are often a neglected area of the body. During relaxing, your scalp will be surrounded by smelly, harsh chemicals. Don't forget to show it some love in order to promote healthy hair growth.
Take a biotin supplement once a day. Though evidence is insufficient, it has been observed that biotin promotes healthy hair. Biotin is found naturally in dairy products, meat and fish, though in small amounts.
Protect your hair from heat. After relaxing, it is best to not use heat styling of any kind on your hair. It will amplify the dryness and can cause a large amount of breakage.
Style without heat. Styles such as braids do not need heat and allow braids one day, and beautiful waves the next. This cuts down on shampooing amounts and allows your hair to regain strength after the first few days of your relaxing.
Get regular cuts and trims. Split ends are a part of life, no matter how well you care for your hair. After a tough processing like relaxing, already-beat-up ends can be brutalized. Regularly trim your split ends to prevent the damage from travelling up into your hair.
