Women are obsessed with the Keratin Complex Smoothing Therapy.

In spite of the downturned economy and the fact that salon clients are waiting longer between cuts and colors, the Coppola smoothing and straightening treatment is one salon sector that continues to grow in popularity. The treatment infuses hair strands with keratin, which cuts up to 95% of frizz and curl, and leaves hair silky and soft.

While other Brazilian straightening treatments can contain significant concentrations of formaldehyde, The Keratin Complex is the gentlest version available on the market, with less than 2% of chemical in the formulation.

And now you can take the benefits of keratin therapy home with you.

Keratin's Intense Rx is a new serum infused with 25% pure keratin to help strands rebuild strength and elasticity by clinging to protein bonds to restructure the hair. Think of it as filling in a pothole-riddled road with cement; you're left with a smooth, sleek surface.

The serum can be applied as a weekly deep treatment, after shampooing and towel-drying so that the keratin can fill in strands without a blocking layer of conditioner. The product can also be applied over regularly washed and conditioned hair as a styling aid to add managability and shine to locks.

Either way, the keratin works on 'regular' hair that hasn't had a straightening treatment, as well as the lucky frizz-free gals who have had the salon treatment.

We put the serum to the test on our untreated hair, and were immediately impressed even before the first pump. The ingredient list on the bottle reveals only a few names, with keratin coming in second after water. There isn't an endless listing of every build-up causing silicone known to mankind like most hair serums; only two light versions in fact, cyclodimethicone and dimethicone.

We applied the serum as a styling aid on freshly washed and conditioned hair, and instantly felt strands were silkier and more managable. Frizz was reduced, and our drying time impressively downgraded by a few minutes.

The only 'ouch' came when we saw the price - between $40 - $120, depending on the size you get. Great hair apparently doesn't come cheap.

Salons will also offer this treatment as an in-salon experience - which basically involves the stylist applying the serum to freshly washed strands, putting a plastic cap on, and setting you under the dryer for about 15 minutes.

To try your own version at home, simply wash hair with shampoo only, towel dry, apply two to four pumps of serum, plastic cap, and run a hair dryer over your head for several minutes.

We're addicted.
