I believe the price of keratin treatments have come down, but please consider spending $175 on the following products to achieve healthier hair and similar styling finish.
1) KeraCare 1st Lather Shampoo or any clarifying shampoo.
2) Pureology Nanoworks shampoo (luxury line - $55 for this one bottle, but worth it!)
3) Pureology Supersmooth condition (skip this conditioning step- if you have fine hair. The luxury shampoo has conditioner in it.)
4) Spray a generous amount of the Joico Leave-in detangler and distribute a small amount of the Pureology elixir for slip. Blow-dry. You should achieve a nice straightness.
Then use Pureology Shinemax sparingly throughout and touch up any areas with a curling iron. Follow with Aquage Beyond Shine spray to tame any flyways! By the third try at this, your hair should be improving in health without all the flat ironing . . .
