Permanent Hair Straightening & Keratin Smoothing

Circles on Fitzgerald provides the most professional keratin hair straightening Perth has to offer. Our hair straightening and smoothing treatments will make your straight hair look more natural when compared to the use of a flat iron.

Agi One Next Gen Smoothing System

Agi One is a new technology smoothing system. It contains nano particles that condition and shield the hair while reducing frizz.

Agi One smooths the hair by releasing a nanoparticle into the hairshaft to repair hair from the inside out, whilst simultaneously forming a protective film around the hair shaft. Under thermal action, the film crystallises on the hair surface (thermal crystallisation), homogenising and releasing even more conditioning agents into the hair.

Agi One systems contains coconut oil for added hydration and incredible shine. The in-salon treatment can be done in under 2 hours, and will last between 3–5 months.

Keratin Treatment Perth

At Circles on Fitzgerald we use Jean Paul Mayne products for our keratin treatment. Keratin is designed to relax curly and frizzy hair. A professional keratin treatment will greatly reduce the time of your daily hair straightening routine. The treatment lasts for between 4–6 months depending on what your hair routine is. For example the more you shampoo your hair, the quicker it will wear off.

Sulphate and sodium chloride free shampoo is recommended for the keratin longevity in the hair.

If you use a flat iron to straighten on a daily basis, Jean Paul Mayne keratin will also improve the health of your hair. Once we have achieved the straight and smooth look you have always wanted, you can stop damaging your hair by using a flat iron.

X-tenso Loreal Chemical Relaxer

Our X-tenso Loreal relaxer breaks down the bonds in your hair. This changes it’s shape and makes it smoother and less wavy/curly. Chemical relaxers are designed to make hair smoother and easier to manage for people with strong curly hair that needs something extra to control it.

We recommend visiting our salon every six months to touch up your roots and keep your hair as smooth and manageable as we can.
