Dry and greasy dandruff
Dandruff can be considered as a localised dermatitis and is characterised by excessive flaking. Normally flaking of the scalp occurs to slough off flattened dead cells, but sometimes the process becomes intense in the presence of both oily and dry hair. Depending on the 2 cases there can be greasy horny scales or dry horny scales that leave no trace. It can last for long periods, regress or continue for one’s entire life if not treated. Some cosmetic habits like the use of aggressive products may make the problem worse. Damage from dandruff manifests itself on the hair, causing it to fall out, and on the scalp, with itching and infections.
