Hair Rebonding
generally , Our hair curls because of there is sulphur bonds in our hair. Rebonding will break down the sulphur bonds by heat and chemicals. During rebonding, keratin is added on the surface of the hair. Interferon alpha is a drug used to modify hair follicles and is used in rebonding but it only damages the hair texture. Neutralizers are used to stabilize the hair. rebonding requires at least 3 hours to complete and its is expensive depending on the length of our hair. nowadays , alot of ladies and even guys go for rebonding as people get more vain in nowadays. although reonding is nice , it also damages our hair.
