Despite the variety of haircuts – curls, bobs, pixies, sesson and others, ladies with short hair are limited in the choice of hairstyles. Medium and long strands can be gathered in a ponytail, bob or braid. Short haircut the same need to lay every morning, otherwise hair will look sleek, and its owner – not groomed and gray. Perming short hair – a great way not only to refresh the image, but also for a few months to save yourself from having to spend a lot of time every morning in front of the mirror, armed with a hair dryer, curling iron or brush.
Types of chemistry on short hair by the used compositions
If in the 90-e women curled their hair in only one way – through a curl, then today there are several methods of chemical perm – particularly effective, gentle and even therapeutic, depending on the compositions used.
Acidic chemistry is so called because it uses acids as active substances – tartaric acid, glycolic hydroacid, thioglycolic acid – personally or their combinations. They are effective in creating curls, which are clear, elastic and last up to 6 months, but they are very drying hair. Therefore, this method is very rarely used in modern hairdressing salons, only on very oily scalps.
Alkaline chemistry is designed to curl stiff and unruly hair. The active ingredient is an ammonia compound. When performed on a healthy and strong hair, observing the recommendations of the instructions and curing not more than the prescribed time, the procedure is less harmful than when using acids. But if the unprofessional conduct of alkaline perms lady can lose her hair in the literal sense of the word. Curls turn out strong and on short haircuts hold for 4-6 months.
Of the traditional options of chemistry, the neutral method is the safest. The active ingredient is glyceryl monothioglycolate. It practically does not harm the hair, so it is in demand for the perm of weakened and colored hair. The disadvantages are a short durability (up to 3 months even with short haircuts) and haphazard straightening of curls.
For curling short hair, hairdressers recommend carving or light chemistry, which includes cocamidopropylbetaine and keratin in the preparations used. The first reagent itself is quite aggressive, but it does not penetrate into the structure of the hair, acting on the surface, so it is not strongly damaged. The result lasts for 2-3 months, and the form of curls is determined by the shape of bobbins used.
The latest innovation in hairdressing is bio-hair curling, which allows you to create completely different curls (from Hollywood waves to small curls), lasting for a long time. The main advantage of biological methods is their safety and therapeutic effect on the hair. The main active ingredient in all compositions is cysteamine, which is similar to cysteine, a protein present in the structure of the hair.
