What is organic hair straightening?
Organic hair straightening (also known as organic keratin) is a treatment that restructures the hair fibre to eliminate frizz and leave hair completely smooth, shiny and manageable for up to 6 months — without using formaldehyde or harmful chemicals.
At Ana Gago Hairsalon we use formulas that are 100% formaldehyde-free, compatible with coloured, highlighted or chemically treated hair. Before each treatment we perform a hair diagnosis to choose the right formula for your hair type.
We work exclusively with Nashi Argan products — vegan, cruelty-free formulas that not only eliminate frizz but also nourish and protect the hair fibre, leaving it visibly healthier after every treatment.
