It's better to have a perm or a cold perm. Girls who have done a perm must have a deep understanding. Perm can be divided into perm and cold perm. Many girls are struggling to choose between cold perm and hot perm, so let's go and see whether perm is good or cold perm.
Perm perm or cold perm 1 The first perm becomes the virgin hair in the industry, which means healthy hair, no perm or dyeing. The first perm of this kind of hair, as long as it is not a novice, can basically perm healthy curly hair. As for the final effect of hairstyle, it depends on the aesthetic level and technical level of the operator.
Therefore, we must find a barber with good perm skills and rich experience to minimize the damage of perm to hair. Because the perming water is not well mastered or improperly operated, it has a great influence on hair quality. Some hair stylists with poor skills can waste a virgin hair at a time, so it is too important to choose who to perm you.
Whether it is a perm or a cold perm, improper operation will damage the hair, and the damaged hair cannot be restored to the state before perm. Be sure to consult before perming, choose perming water and hairdresser suitable for your hair, and let your hair get the greatest care. According to the normal technical operation, the bigger the perm, the smaller the influence on the hair quality, and the smaller the curl, the easier the hair is to be short-tempered. After ironing, you must insist on hair mask care, which is of great benefit to your hair.
If it is long hair or medium hair, it is recommended to choose a perm. If you have short hair and like the fluffy and full effect of perm, it is recommended to choose cold perm.
Perm Perm or Cold Perm 2 Difference 1: The softening degree is different.
Cold perm medicine changes the chain bonds of hair by 70%-80%. After perming, the hair needs to be moisturized to fully show the curl. If dried naturally, 20%-30% of the chain bonds will return to straight hair. Therefore, it is necessary to use styling products such as elastin or gel to assist moisturizing in the later stage.
However, the perm agent can change the secondary bond of hair by 100%, and it needs to be dried to show elastic curl. However, the consolidation period is within 15 days after scalding, so it is best to use the shaping products that increase elasticity.
Difference 2: The process is different.
Cold stamping: plasticity-softening-setting
Blanching: softening-plasticity-setting
And the heating temperature is different.
During cold ironing, if the room temperature does not reach 15 degrees, we can properly carry out external heating and control the temperature below 40 degrees. Because excessive cold perm and heating will cause excessive loss of protein in hair, the curl of perm will be inelastic.
Perm must be heated in order to recombine the secondary bonds cut in the hair in memory, and this chain bond needs to be between 100 degrees and 140 degrees to produce memory recombination, so the heating temperature should be controlled between 100 degrees and 140 degrees, and the water should be dry.
Difference 3: For different hair qualities.
Cold perm is a method of scaling and perming, and the effect is very good after healthy perm. After the damaged hair is permed, the texture will be loose and rough, or even broken.
Perm is a method to seal the hair scales. Originally made for damaged hair, it can supplement the internal nutrition of hair to the greatest extent and reduce the damage to hair.
