Keep the hair clean. We suggest that you wash the hair at least once or twice a week with warm or cold water. Please wash the hair immediately after swimming, spa, exercise, and etc. When dirt and sweat accumulate, hair tangles. Too much leave-in conditioners and other hair care products will create a build up on the hair and will cause it to tangle faster. If the hair feels dry or heavy with build up, wash it with good shampoo & conditioner. Before washing the hair, spray mixture of conditioner and water and brush the hair from bottom up. You must gradually wet the hair down and brush it gently before you completely wash the hair. If the hair is very dry and a lot of water is added at once, hair will swell up like sponge and tangle! Therefore, it is important to gradually wet the hair and brush it. After wetting the hair, add shampoo and conditioner and brush thoroughly. Be sure to wash and brush the hair in one direction. Rinse the hair completely with water and towel dry. It is best to air dry the hair but you can also blow-dry with low to medium heat. Make sure you brush the hair daily and apply some leave-in conditioners so that the hair is soft and moist. A good leave-in hair treatment can keep the hair from drying. But remember not to put too much otherwise there will be a build up and make the hair feel too heavy. If the hair feels too dry or heavy with too much hair care products, you should wash the hair completely by following steps 2 and 3. When swimming, always wear a cap to prevent prolong exposure to chlorine or salt water which causes the hair to tangle. Always wash the hair right away with shampoo and conditioner after swimming in both types of water. When going to the spa, the hair should be brushed out completely and should be wrapped in a cold wet towel. Make couple of big braids when going to sleep, swim, or exercise (please untangle the hair before making the braids). NEVER SLEEP ON WET HAIR. Make sure the hair is completely dry before going to bed. You can also make a leave-in conditioner at home by diluting conditioner (10%) with water (90%). Apply the mixture lightly onto your hair and brush the hair from the end to the top near the scalp. Although it is important to apply leave-in conditioners to keep the hair from dryness, it is important to keep the hair clean by washing the hair about twice a week so that it will not create a build up. It would be advisable NOT TO TINT, COLOR, PERM OR DO ANY EXTRA CHEMICAL PROCESSES because it has already been treated. Please be extra careful with blonde and other light colored hair. They are more chemically processed than the dark hair. Therefore, we will not be responsible for the outcome.
