What’s The Difference Between Hot And Cold Perms?

Before getting your hair permed you need to know about the various types of perms, and what they do to your hair in the course of treatment.

Perming is a method that takes away and rebuilds hair using disulfide bonds, forming the desired curls in your hair. There are two main ways to accomplish this: hot  and cold perms.

Cold perm is the process of using an alkaline perm solution, typically made up of ammonium thioglycolate. The solution breaks the disulfide bonds when your hair is wound up around a rod for perming. Hot perm is the identical as cold perm, but in this case, it uses an acidic solution to break down the disulfide bonds.

Hair that has had hot perms tends to be more curly when dried. However for cold perms, more styling is required, such as applying curling creams and gels is required to get the same result. That means hair that has been through the hot perm will need considerably less care when compared to a cold perm. 

One disadvantage to the hot-perm is hot rollers can't be kept from getting too close towards your hair's scalp. Therefore, if you're seeking to lift your hair roots to increase body or volume generally, it is advised to opt for root perm and not a hot perm.

With the advancements in hair technology accessible today, perms appear more natural and give it a soft appearance. Salons today offer a vast variety of perms to suit your hair. It is crucial to make sure you research before making your decision.
