Keep your hair clean. Some people wash their hair everyday, others once or twice a week. How often you wash your hair is left up to you. Just be sure to choose a good moisturizing shampoo and conditioner.
You should deep condition your hair atleast once per month, I recommend once a week. Choose a deep conditioner with protein. Your hair needs protein to keep it’s moisture balance.
After you wash and condition your hair, always apply a leave-in conditioner. For thick textures, the creamy leave-ins work best. Fine hair ladies might find that the creams are too heavy and weigh their hair down. If this is the case, you will want to opt for the liquid leave-in conditioners.
Air dry your hair if time allows, if not, dry on a low setting and use a heat protectant.
If you choose to use hot curler, hot combs and/or flat irons, you must monitor the temperature to prevent scorching your hair.
Each night you should add some creamy moisturizer to you hair focusing on the hair line, the nape and the ends of your hair. Whether you wrap your hair or not is irrelevant, just be sure to either cover it with a silk/satin bonnet or scarf, or invest in some satin pillow cases. This will prevent your hair from drying out and breaking while you are sleeping.
You should find an oil that works well for your hair. Some oils tend to be heavier than others. Jojobo oil is my personal preference. Apply between a dime size and a quarter size amount of oil (depending on the thickness and texture) to your hair each morning.
Set a routine and your hair will flourish in time. Be consistent and your hair will grow to lengths you never achieved before.
Be blessed and keep it growing!
P.S: Moisture, moisture, moisture. We cannot stress on that enough. Your hair needs water, specially if you are natural. The natural oil that your body produces does not travel up to the hair shaft easily if you are natural. Therefore, you need to moisturize your ends at least once a day.
