Dread perms usually cost in the range of $300–$400 at a salon, and although pricey, often prove to be the easiest and most professional way of creating dreadlocks. Another option is to buy a home-perm kit, as these will only cost $10–$20, with a similar, if not better result.

The curls may last a number of months, hence the name. Perms may be applied using thermal or chemical means.
Another type of "no-lye" relaxer uses ammonium thioglycolate, which is also known as perm salt for its use in permanent waves.

The thioglycolic acid in the perm solution reduces the disulfide cystine bonds in the cortex of the hair. [2] In a sense, the thioglycolate removes crosslinks. After washing, the hair is treated with a mild solution of hydrogen peroxide , which oxidizes the cysteines back to cystine .
Perms and relaxation using relaxer or thermal reconditioning involve chemical alteration of the internal structure of the hair in order to affect its curliness or straightness. Hair that has been subjected to the use of a permanent is weaker due to the application of chemicals, and should be treated gently and with greater care than hair that ...
Chemical depilatories are indicated in the treatment of hirsutism in polycystic ovary syndrome. Depilatory ointments, or plasters, were known to Greek and Roman authors as psilothrum. [3] In Jewish lore, King Solomon is said to have discovered a chemical depilatory made from a mixture of lime and water and orpiment (arsenic trisulfide). [4]
