Relaxers, or straighteners, “work by breaking chemical bonds in curly hair,” according to the Kids Health website. Relaxers containing lye can cause skin irritation and hair breakage, and even “no lye” relaxers can cause problems, the site adds. One of these problems is the annoying itchiness from a dry scalp or dandruff. If you have relaxed your hair and have resulting dandruff, there may be ways to control or cure it.
Use a teaspoon of freshly squeezed lime juice after shampooing, and thoroughly rinse your hair with warm water. The lime will remove any sticky residue from your hair, and loosen and rinse away dry particles from your scalp. A clean scalp discourages the accumulation of dead cells. You can also remove dandruff with a combination of lime and gooseberry juice. Massage a few teaspoons of the mixed juices into your scalp every night before going to bed.
Use a commercial dandruff shampoo containing salicylic acid, zinc tar or selenium sulfate to help control your dandruff. During the shampooing process, take the extra time to massage your scalp for about five minutes. This process loosens the flaking particles on and beneath your scalp. Rinse very well with a liberal amount of warm water.
Soak two tablespoons of fenugreek seeds in water and allow it to sit overnight. Mix it up, then stir and grind it into a paste in the morning. Apply the paste to the scalp and leave it on for a half-hour. Rinse with warm water, shampoo and condition the hair as usual. Keep in mind that the hair should be brushed daily to encourage circulation and remove any additional flakiness. Repeat this treatment twice each week.
