Experts teach you how to brush your hair properly without breaking the strands

RIO - In the last edition of the CES technology fair, in Las Vegas, in the first week of the year, a novelty in relation to beauty drew attention: a smart hairbrush , which warns you if you are putting too much force on the act or if it is breaking the wires.


Called "Hair Coach", the launch of L'Oréal's Kérastase is a response, according to Guive Balooch, the group's director of research and innovation, to women's concern with fiber breakage.


But how can such a common act bring harm? How, then, should it be done? We asked for help from dermatologist Ana Carina Bertin, from São Paulo, and from trichologist Viviane Coutinho, from Clínica Juliana Neiva, in Rio, to answer the main questions on the subject.


Why, sometimes, when brushing the wires, do they break?


We don't realize it, but the act of brushing the wires is an aggression to the capillary material.


"When we brush very hard, we exceed the elastic capacity of the thread and it breaks. The thinner threads by nature or by chemical processes resist even less, so they should be less stretched", explains Ana Carina.


What is the biggest mistake made when brushing the wires?


The first thing to do is choose the right tool, according to Viviane:


"The combs are ideal for detangling, especially when they are wet, and for curly or curly textures. The brushes are ideal for straight and drier hair. Wanting to detangle your hair with the brush when they are still wet is one of the biggest mistakes ".

Does brushing during the bath help to reduce breakage?


It does help, since the wet thread is more elastic than the dry one. If it is washed with conditioner, then even better.


Is it better to start untangling the roots towards the ends or isolating the ends first?


The logic is always from the bottom up, don't forget.


"Brushing should be done in three phases: tips, middle part of the hair and, finally, the root", teaches Ana Carina.


What types of comb / brush are best for a healthy process?


There is no rule, as it all depends on the type of hair. Straight, fine hair calls for a Best Brushes for Fine Hair such as wooden comb or natural fiber brush, which minimizes breakage. The thick ones need wide combs with spaced bristles.


"I only recommend a fine comb for men with short, thin hair," says Ana Carina.


Why and at what frequency should combs and brushes be cleaned?


Many people do not pay attention, but the bristles that pass through the hair end up accumulating residues of products that we cannot see. The environment, therefore, is conducive to the accumulation of mites, fungi and bacteria that can affect the scalp.
