For the first 72 hours, keep hair completely dry, straight, and free of ties, clips, or tucking behind your ears. After that, wash only 2–3 times a week with a sulfate-free, sodium-chloride-free shampoo. With proper aftercare, a keratin treatment stays smooth and frizz-free for two to four months. |
A keratin treatment is one of the best investments you can make for smooth, manageable, frizz-free hair especially through an Austin summer. But the treatment doesn’t stop working the moment you leave the salon. The right aftercare is what turns a fresh-out-of-the-chair result into months of sleek, healthy hair. Here’s exactly what to do.
The first 72 hours: the make-or-break window
The three days after your appointment are the most important. The keratin is still bonding to your hair’s cuticle and is highly sensitive to moisture, pressure, and friction. During this window:
- Keep your hair completely dry no washing, swimming, or getting caught in the rain.
- Keep it straight and loose no ponytails, buns, clips, headbands, or tucking behind your ears, which can create permanent creases.
- Skip styling products and heavy sweating, including intense workouts, saunas, and steam rooms.
If your hair does get damp, gently blow-dry it straight on low heat right away.
Choose the right shampoo and products
Once the 72 hours are up, your products matter more than anything else. Standard shampoos strip the keratin from the hair shaft, cutting your results in half. Use a sulfate-free and sodium-chloride-free shampoo and conditioner made for treated hair, and wash only two to three times a week. Over-washing is one of the fastest ways to lose a treatment early.
How long does a keratin treatment last?
With good aftercare, most keratin treatments stay smooth for two to four months, depending on your hair type, how often you wash, and your lifestyle. Touch-ups are typically recommended every three months. During a touch-up, your stylist treats new growth and refreshes the mid-lengths and ends a great time to trim any split ends, too.
Workouts, swimming, and Austin humidity
After the initial 72 hours you can return to normal activity, but a few habits protect your investment. Manage hairline sweat with a keratin-safe dry shampoo or a cool-water rinse and leave-in. Before swimming, saturate your hair with fresh water and consider a swim cap chlorine and salt water both strip keratin. And because Austin humidity is exactly what keratin defends against, sticking to sulfate-free products keeps that frizz-free finish going strong.

Frequently asked questions
How long do I have to wait to wash my hair?
Wait at least 72 hours (three full days) before your first wash so the keratin can fully bond. Some keratin systems recommend waiting a little longer, and we’ll let you know which applies to your treatment.
Can I tie my hair up after a keratin treatment?
Not during the first 72 hours. Hair ties, clips, ponytails, and even tucking your hair behind your ears can create permanent dents while the treatment is setting.
What shampoo should I use after keratin?
Always use a sulfate-free, sodium chloride-free shampoo. Sulfates and salt can strip away the keratin treatment and shorten the life of your results.
How often should I wash keratin-treated hair?
Washing your hair two to three times per week is ideal. Over-washing can cause the treatment to fade faster and reduce its longevity.
Can I still work out or swim?
Yes, after the initial 72-hour waiting period. Rinse away sweat with cool water when possible, and protect your hair from chlorine and salt water by wetting it with fresh water before swimming.
How often do I need a touch-up?
Most clients schedule a touch-up about every three months to treat new growth and keep their hair smooth, healthy, and frizz-free.
Will keratin help with Austin humidity and frizz?
Absolutely. Keratin treatments are designed to reduce frizz and improve manageability in humid weather, making them a favorite choice for our Austin clients.
