Many women with curly and frizzy hair still resort to guanidine to keep their hair straight. However, excessive use of the product can result in dryness and lack of movement, and some end up opting for the progressive brush. But great care is needed to know which component is compatible with the chemistry.

"Whoever has hair straightened with guanidine hydroxide cannot opt for a progressive brush based on ammonium thioglycolate. The two components are not compatible and results in hair breakage instantly", explained hairdresser Jacqueline Cláudia.

Guanidine is indicated for women with very curly hair

Guanidine hydroxide has the power to successfully smooth frizzy hair. The process is a definitive smoothing and requires retouching from 60 to 90 days only on the grown parts. Therefore, if you invest in the procedure, know that your hair will be completely straight for a long time.

"Before straightening, always do a strand test to make sure your hair is healthy enough to receive the product. Then make a capillary schedule of hydration, nutrition and restoration to leave the strands nourished and shiny and wait for 15 to 20 days to color, avoiding shades that require a 30-volume oxidizer," said the expert.

After the guanidine, you can do a progressive keratin brush

After formaldehyde was banned by Anvisa - the chemical can cause various damages to health, such as cancer and respiratory problems - many progressive brushes were launched. The one based on keratin is ideal for women with curly and frizzy hair who already have their hair straightened with guanidine.

The two substances are compatible and you won't risk having a chemical cut. But know that it is very important to maintain the treatment routine so that the locks do not become dry and porous. Progressive brush lasts less than guanidine, as it is eliminated during washes. The touch-up procedure takes place from 3 to 6 months.
