Brazilian hair straightening is a real boon for busy contemporaries. It helps to save precious time in the morning without wasting it on styling your hair.

The essence of the procedure

The keratin straightening procedure is performed using natural protein – a component of the hair. It consists of simple amino acids that fill 75-96% of the rods. The element of the structure of the strands – keratin, as scientists have found, determines the shape of the curls, which can be straight or curly.

The essence of hair straightening with keratin is the simultaneous straightening of the strands and associated care. During the procedure, the therapeutic composition of the products saturates the rods with liquid protein and a set of vital substances – vitamins and minerals, natural extracts and biopolymer materials. As a result of this care, even naughty curls become smooth and silky.

These advantages of keratin hair straightening will be able to appreciate the owners of any type of hair, except for thinned and brittle, the volume of which can be significantly affected after smoothing. However, there are nuances:

  1. For long and medium curls, keratin hair straightening is performed most often.
  2. Natural goat or vegetable keratin may not straighten African curls or hair after permanent curling. It will need to be repeated or a stronger chemical preservative applied.
  3. For short hair, keratin straightening is performed only in cases where their length exceeds 10 cm.This is due to safety: keratin pairs should be at a distance of at least 2 cm from the scalp.
  4. The technique of keratin straightening hair, cut in the style of a bob or bob-bob, provides that in the trimmed area, the strands are not processed if their length is less than 8-10 cm. Otherwise, when pulled with a hot styler, there is a risk of getting a skin burn.
  5. Owners of fine hair should consult a professional. If the strands filled with keratin create density, tighten the hairstyle without significant loss of volume, then you can try the American, more gentle method of alignment.

Harm and disadvantages

Of the minuses of keratin hair straightening, users note:

  • weighting the strands. Long curls in this case begin to lose the rods;
  • frequent contamination and loss of volume. At the same time, you should not wash your hair too often, since the straightening effect will quickly disappear. It is better to wait for the hair to adapt;
  • the need to be present in the cabin for 3-5 hours, breathe harmful vapors. Some women complain of shortness of breath, tears, and allergic reactions.

Synthetic counterparts on supermarket shelves contain a little keratin and a lot of preservatives. Is the use of cheap analogs useful? This is fraught with excision of the ends of the hair and further destruction. Quality keratin, derived from sheep or goat six, is a valuable organic product, so it costs a lot. Only specialized salons that have received a license from the manufacturer can work with natural formulations.

If hair restoration is required to be combined with smoothing, then it is better to use natural products without harmful components – formaldehyde derivatives. In cases where healthy hair just needs to be smoothed, then you can resort to a preparation containing a chemical preservative – formalin.

Does keratin straightening spoil hair? When using low-quality formulations or violation of the process technology from high temperature, the tips can be cut, which will cause the gradual destruction of the structure of the curls and their loss.
