Keratin Complex Natural Keratin Smoothing Treatment for Blonde Hair

Got a bottle of Keratin Complex Natural Keratin Smoothing Treatment specifically for blonde hair. This is the 4oz size, still sealed in the plastic wrap. It's the professional stuff meant for smoothing out frizz and making hair way more manageable. I bought it but never ended up using it so it's just sitting around. Good if you do your own hair or are a stylist looking for a deal on a fresh bottle.
