Every time a barber has a perm, he will say how good a perm is. For laymen, I really don't know the difference between a perm and a perm.

Advantages and disadvantages of hot and cold ironing

Both cold perm and perm are the most commonly used perm methods in hair salons. Both methods can curl hair, there is no difference between good and bad, mainly depending on what hairstyle to perm.

Cold perm belongs to the most traditional perm method, and most of the classic perm works in the past came from cold perm.

Perm is a special perm method, which needs to be softened with special medicine, and then the hair is curled on a special curling iron for high temperature setting.

Perm is more suitable for perming hair styles with big curls, big bends and big waves, especially for long hair or medium-long hair.

The advantage of cold ironing is that the winding method is flexible and the use of liquid medicine is very simple. It can be permed from the root to the tip of the hair to obtain the maximum fluffy effect, and the effect is best in wet hair state. The disadvantage is that after drying, the curly hair will become bigger, the texture of the hair will become worse, and even a sense of recklessness will appear. It is necessary to use moisturizing styling products to show the texture and elasticity of curly hair, and the effect will be slightly worse when perm large curly hair.

The advantage of perm is that the texture and elasticity of hair after perm are super good, especially in perm, perm and wavy hair, which has perfect expressive force. And nursing is relatively simple. Most burns do not need to use styling products, and will be shaped after drying. The disadvantage is that it is not suitable for perming short hair, perming hair roots and curly hair close to the scalp, and the fluffy effect of perming hair roots is relatively poor.
