What to know

Keratin Treatment at Salon Envy®

San Antonio sits in a humidity corridor between the Gulf Coast and the Hill Country. Summer months regularly hit 75 to 90 percent relative humidity, and even the spring and fall bring enough moisture to turn styled hair into a frizz halo by lunchtime. Keratin smoothing is the most effective solution we offer for this problem, and our Wurzbach Road location performs these treatments multiple times per week.

We carry two formulas. The Brazilian Blowout is a faster treatment (about 90 minutes of active service time) that reduces frizz while keeping your hair's natural texture and movement intact. It lasts 10 to 12 weeks on average. The full keratin smoothing treatment takes about 2.5 hours and delivers more dramatic results: significantly smoother texture, 50 percent less blow-dry time, and 12 to 16 weeks of frizz-free results even in peak San Antonio summer heat. Both are formaldehyde-free and color-safe.

The consultation at the start of your appointment determines which formula your stylist recommends. Fine hair with a slight wave gets a different concentration than coarse, tightly curled hair. Your stylist also considers whether you color your hair, because the keratin needs to be applied after color, not before. If you are due for a color touch-up, we can do both in the same appointment by scheduling a longer block.

Pricing at our San Antonio location starts at $250 for short hair. Shoulder-length hair runs $275 to $325. Long or extremely thick hair falls in the $350 to $400 range. The price includes the treatment, a blowout, and the flat iron seal. Aftercare products (sulfate-free shampoo and conditioner) are sold separately at $25 to $35 each and are required to get the full lifespan out of your treatment.

The 48-hour rule applies to every keratin client. For two full days after your treatment, do not wash, tie up, clip, or pin your hair. No sweating. No rain. This is the curing window. Breaking it compromises the seal and shortens your results. Your stylist will explain everything before you leave and send you home with a printed care guide.

Book your keratin appointment at (210) 660-3339 or online. We recommend scheduling at least a week ahead, as our keratin time blocks fill quickly during spring and early summer.
