When I left, I had chemical burns and scabs all over my scalp. My hair? It was shiny, smooth and so, so straight, and I was obsessed. As Maynard tells me, there are many issues involved with the treatment: breathing in harsh chemicals, damage to the hair, and much more. Instead, the straight texture stays in place as new hair grows in at the roots. Meaning without maintaining the treatment on a monthly basis, I had kinky curls growing in at the top of my head, and pin-straight hair to follow.

That meant flat-ironing my hair on a daily basis and repeating the treatment, causing more damage than what had already been done — something Maynard says is a common mistake. After returning time after time, I ended up with a small set of bangs — not because I cut them, but because heat and chemicals broke off the front section of my hair.

The head of hair that I was once barely able to wrap an elastic band around twice thinned out due to the breakage, and turned into a loose, frizzy wave that never looks quite right. And as for my beautiful curls? It's possible that if I had quit while I was ahead — that is, realized that having pin straight hair wasn't worth the process — the long-term effects on my hair may have been different. It's also possible that the treatment damaged my hair, but that it also changed with age, over time.

And make sure to ask your stylist about strengthening add-ons like Olaplex, she advises. Your stylist will recommend you have touch-up treatment usually every four-six months, but the exact interval will vary depending on the degree of curl and length of the hair. Your unique hair texture, speed of growth, and ability to work with the new growth will ultimately determine the length of time for you. Usually it is only the regrowth that will need treatment. The average time of a Yuko is around 4 hours but could be more for especially longer or thicker hair.

Only when you have significant regrowth might you decide to straighten the roots of your hair if you want the super sleek look. Styling time may increase slightly as your new hair grows back, but should never take as long as your pre-straightened time. Straighteners will no longer be necessary for you to have straight hair but some clients may choose to use a straightener to polish their hair or to achieve a desired style. Strictly no hair grips or hair ties should be in your hair for a minimum of 48 hours after your treatment as the hair is still sensitive and this can leave marks — this also means there can be no washing!

You should also not colour your hair for at least 2 weeks after having the straightening done. Call us on Oxford or Bicester to your Yuko consultation. For our price list click here.
