Alkaline
Hair perming lotion typically contains alkaline chemicals, such as ammonium thioglycolate, to break and restructure the bonds in the hair shaft. This process helps the hair to take on a new shape when curled or styled.
Suntan lotion is typically neutral in pH, meaning it is neither an acid nor an alkali. It is designed to be mild and compatible with the skin to provide protection from the sun's ultraviolet rays.
The acid commonly found in cold wave solutions is thioglycolic acid. It is used to break the disulfide bonds in the hair, allowing for restructuring of the hair's natural shape during the perming process.
A weak acid like citric acid or vinegar would be more suitable for neutralizing leftover alkali in hair, as it is gentle and less likely to cause damage or irritation to the scalp and hair. Strong acids can be too harsh and may lead to further damage to the hair.
Acid is added to the hair after using alkali solutions to help neutralize the pH level of the hair shaft and close the cuticle. This helps to restore the hair's natural pH balance, prevent damage, and seal in moisture and nutrients.
Acid. Alkaline waves processes faster without heat. Acid waves processes slower and are more gentle on the hair and leaves your hair in a better condition.

Currently there are no lasers that are designed to perm hair. The perming process uses chemicals to change the bonds between certain amino acid molecules in hair. Currently, the laser energy is both too strong and non-specific so it will only damage hair. Perhaps in the (not too distant??) future they will design lasers with hair perming in mind that will either directly produce the perming effect or augment the curent array of chemicals that perm hair.
