What is hair botox?
Hair botox has nothing to do with injections. It is a deep hydration and nourishment treatment that fills damaged hair fibres, eliminates frizz and adds shine and softness. The name comes from its “filling” effect on the hair — similar to aesthetic botox.
Unlike organic straightening, hair botox does not permanently alter your natural curl pattern. If you have curly or wavy hair, you keep your waves — the treatment just makes them softer and frizz-free. Results last 2–4 months.
At Ana Gago Hairsalon we use Nashi Argan products — vegan and cruelty-free — to ensure the best results while keeping your hair healthy and protected throughout the process.

Does hair botox straighten curly hair?
No. Hair botox does not alter your natural curl pattern. Curly or wavy hair keeps its shape — waves simply become softer and frizz-free.
Is hair botox safe for colour-treated hair?
Yes. Hair botox is fully compatible with coloured, bleached or highlighted hair and is often recommended after colour services to restore moisture.
What is the difference between hair botox and keratin?
Keratin permanently relaxes the curl; hair botox is a deep conditioning treatment that fills the fibre and eliminates frizz without altering natural texture.
