Karen Guerreiro, hairdresser: “Gray hair has to be cared for by alternating two shampoos, one silver and one anti-hair loss, and washing it only twice a week”

Posted on 22 August 2026

Gray hair continues to generate a lot of debate, but if there is one thing that is clear, it is that the vision of gray hair has changed and now there is much more emphasis on caring for it and integrating it rather than covering it with dye just because it has to. Hairstylist Karen Guerreiro explained to the Semana publication that gray hair needs the same care that we provide to dyed hair.

With this, the expert means that showing off gray hair does not mean that we have nothing to do or wear our hair unkempt. Not at all, gray hair requires its homework to be beautiful. One of the most common mistakes that Karen highlights is thinking that letting gray hair grow means forgetting to use products and go to the hairdresser.

Nothing could be further from the truth, gray hair cannot be left to free will. According to the expert, care begins by choosing the type of shampoo well, taking into account the needs of the hair. To provide volume, hydration or with anti-hair loss treatment.

As the years go by, hair changes, it is not the same at 20 as it is at 40. “Over time, hair becomes more fragile due to hormonal changes,” says Guerreiro. For this reason, the hairdresser advises a more global vision of the problem, reviewing lifestyle habits, diet and of course the products we use for our hair. The important thing is to allow yourself to be advised and find the appropriate diagnosis for the needs of each client. “You must come to the hairdresser, make a diagnosis and use an appropriate shampoo,” explains Karen.

In the case of gray hair, a more specific routine must be followed, which is why the hair stylist recommends that: “You must use two different shampoos. One for fine hair, to clean the gray hair, and another according to the need.” Of course, beyond the shampoo, you must add a hydrating mask, something that will help soften the gray hair.

But like many other experts, Karen Guerreiro also highlights that a haircut is essential when you have gray hair. “There is no need to cut, you can have long hair with gray hair. The concern should be taking care of long, white hair and ensuring that it has density and texture. Women do not have to cut it short,” he points out.

The basic product, violet shampoo

If there is a product that always comes up every time gray hair is discussed, it is violet shampoo. It is undoubtedly a basic to keep gray hair bright and free of unwanted tones, which is why the expert defends its use: “You have to use it because gray hair has an internal reflection and that silver shampoo cleans that reflection,” she comments. Although he also insists that not all gray hair reacts the same, “gray hair that comes from a brown background is not the same as gray hair that comes from a blonde background,” he explains. For this reason, it is important to choose the most suitable shampoo for each case and even alternate different shampoos.

Hair washing is also important

Regarding hair washing, the hairdresser highlights that it is not advisable to wash your hair every day. Doing it two or three times a week is enough, but there is something that is very important, drying your hair well. “If I wash my hair with less than 24 hours between washing and do not dry it, I cause the hair bulb to remain damp and that in the long run causes hair loss,” he adds.

According to Karen, gray hair has many possibilities, we must see it “as a blank canvas, like a work of art that must be sculpted,” she points out. That is why he insists that gray hair must be cared for and pampered as we would with any other type of hair.
