Why Does A Perm Last So Long?

The maintenance & nourishment of the hair after the perm treatment play a vital role. The type of hair also plays a major role in the duration.

Other factors such as hair thickness, hair growth, hair texture, and the length of the hair also influence the duration of perm treatment. Apart from these factors, other aspects influence the duration of the effects.

The use of a strong concentration of chemicals for hair perm treatment will result in a longer duration of the effects. The effects may last for 5 to 6 months.

Hair perm treatment by a professional (with appropriate experience) lasts much longer. This is due to the proper understanding of the procedure, chemical composition, and other aspects by the professional. 

The perm treatment duration increases if the hair is maintained free from frizz and tangles. Proper hydration and conditioning of the scalp also help to increase the perm treatment duration.

Hair perm treatment is a result of a combined effect of various chemicals. These chemicals cause temporary changes in the hair. The composition, concentration, and application of chemicals also influence the duration of perm treatment.

The initial days after hair perm treatment are important. No head bath or shower for at least 3 to 4 days after the treatment. Combing of hair should be strictly avoided for at least a day after the treatment.


Hair perm treatment has permanent effects for a temporary period. All the above-mentioned factors decide the duration. After the end of the stipulated temporary period, the result of hair perm treatment effects will vanish. This means that the individual needs to undergo this treatment again for a revival of the earlier results.

There are only minimal chances that hair perm treatment may last longer than 6 months. Proper hair conditioning, hydration, and care can increase the duration of the treatment by a month or two.
