A keratin treatment is a game-changer for those who want smoother, shinier, and more manageable hair. But the real magic lies in the aftercare. If you’ve just stepped out of the salon with freshly treated locks, your next steps will determine whether that sleek finish lasts two weeks or three months.
In this guide, we’ll break down exactly how to maintain your keratin treatment so you can enjoy long-lasting, frizz-free results—without compromising your hair’s health.
1. Wait Before Washing Your Hair
One of the most important rules: do not wash your hair immediately after your keratin treatment.
- Wait at least 72 hours (or as recommended by your stylist) before shampooing.
- Avoid getting your hair wet—this includes rain, pools, and even sweating excessively.
- If your hair does get wet, immediately blow-dry and flat iron it to preserve the treatment.
2. Use Sulfate-Free and Sodium Chloride-Free Products
Traditional shampoos with sulfates and salts can strip away the keratin coating prematurely.
- Choose a gentle, sulfate-free shampoo and conditioner designed for keratin-treated hair.
- Look for labels that say “keratin-safe,” “color-safe,” or “sodium chloride-free.”
Using the right products makes a significant difference in how long your results last.
3. Wash Less Frequently
Washing your hair less often helps maintain the keratin treatment longer.
- Aim for 2–3 washes per week, depending on your scalp’s oiliness.
- On non-wash days, use a keratin-safe dry shampoo to refresh your roots without disrupting the treatment.
4. Avoid Heat Styling—But Use the Right Tools When Needed
While keratin-treated hair dries faster and styles more easily, excessive heat can still cause damage over time.
- When heat styling, always use a heat protectant spray.
- Use tools with adjustable temperature settings, and avoid going above 180°C (350°F).
- That said, a quick pass with a flat iron can help reactivate keratin and smooth the hair if needed.
5. Steer Clear of Chlorine and Salt Water
Both chlorine and salt can break down keratin and dry out your hair.
- If you swim, wear a swim capor coat your hair in leave-in conditioner or oil before entering the water.
- Rinse hair immediately after swimming and use a keratin-safe clarifying shampoo once in a while.
6. Sleep on Silk or Satin Pillowcases
Friction from cotton pillowcases can rough up the hair cuticle and shorten the life of your treatment.
- Switch to silk or satin pillowcases to reduce friction and help your hair stay smoother for longer.
You can also tie your hair in a loose braid or bun to prevent tangles overnight
7. Avoid Tight Hairstyles Immediately After Treatment
For the first few days post-treatment:
- Avoid tying your hair up tightly or using clips and pins.
- Allow your hair to stay straight and down to set the keratin evenly.
After the initial waiting period, you can style as desired—but avoid hairstyles that pull too hard on your hair, as this can cause breakage.
Final Thoughts
A keratin treatment is an investment in beautiful, low-maintenance hair—but it only pays off if you treat it right. With a few small changes to your routine, you can extend the effects of your treatment and keep your hair looking smooth, soft, and frizz-free for months.
