Keratin-style protein smoothing in Bormujos
Smooth, manageable hair with less frizz, without giving up its shine.
I’m Esther Roldán. At Ethernal, my salon in Bormujos, I do protein smoothing, the service many clients know as a keratin treatment. Before applying anything I assess your hair and explain what you can expect.




Who it is for
It is a service for anyone who wants smoother, more manageable hair and less of a fight with frizz every morning.
Not all hair needs the same. If your hair has been lightened or is sensitive, I assess it first and, if it makes sense, suggest caring for it beforehand.
The amount of product depends on your hair
Before applying anything I assess the length, density and condition of your hair, because that determines how much product it needs and how much time I will spend on it. That is why the service comes in four amounts, from 40 to 100 grams.
If you are unsure how much you need, book the hair diagnosis first and I will advise you.
What the appointment is like
It is unhurried work: between 2 hours and 3 and a half hours, depending on the amount of hair. I recommend booking ahead and coming with time to spare.
Looking after it afterwards
I tell you honestly what result you can expect and how to look after it at home so that it lasts as long as possible, and I recommend the most suitable products to maintain it.
