Why Chemically Treated Hair Needs Special Care

Chemical services temporarily alter the structure of your hair to achieve smoother, straighter, or colored results. While these treatments enhance the hair's appearance, they also make the hair fiber more vulnerable to dryness, moisture loss, and external damage.

That's why adopting the right hair care after keratin treatment or smoothening service is essential. A gentle cleansing routine helps maintain the integrity of the hair while minimizing frizz and keeping it soft and manageable.

1. Wait Before Your First Wash

One of the most important steps in hair care after keratin treatment is following your stylist's advice on when to shampoo your hair. Some treatments require waiting 48-72 hours before the first wash, while newer salon systems may have different recommendations.

Giving the treatment enough time to fully set helps maximize its longevity.

2. Choose a Sulfate-Free Shampoo

The shampoo you use plays a major role in preserving chemically treated hair. Harsh cleansers can remove natural oils and cause smoothing treatments to fade more quickly.

For professional chemically treated hair care, use Matrix Mega Smooth Sulfate-Free Shampoo. Enriched with Squalane, it gently cleanses while helping retain moisture and extend the smooth, sleek finish of salon-treated hair.

3. Follow with a Nourishing Conditioner

Conditioning after every wash helps replenish moisture and smooth the hair cuticle.

Pair your shampoo with Matrix Mega Smooth Sulfate-Free Conditioner, which nourishes the hair without weighing it down. Together, the shampoo and conditioner help improve softness, manageability, and shine while supporting hair care after keratin treatment.

4. Wash with Lukewarm Water

Hot water may feel relaxing, but it can cause the hair cuticle to lift, leading to moisture loss and increased frizz.

Instead, wash your hair with lukewarm water to help preserve smoothness and keep chemically treated hair looking healthy for longer.

5. Don't Over wash Your Hair

Frequent shampooing can reduce the lifespan of salon treatments by stripping away moisture and natural oils.

Most professionals recommend washing chemically treated hair two to three times per week unless your scalp requires more frequent cleansing.

If you're wondering how to wash colored hair, this advice applies as well. Less frequent washing helps maintain both color vibrancy and hair smoothness.

6. Deeply Nourish Your Hair Weekly

Even professionally treated hair benefits from an intensive moisture boost.

Add Matrix Mega Smooth Sulfate-Free Liquid Hair Mask to your weekly routine. Formulated with Squalane, it helps replenish hydration, smooth the hair fiber, and reinforce softness without making hair feel heavy.

This simple step can significantly improve hair care after smoothening, especially if your hair feels dry after repeated styling.

7. Minimize Heat Styling

Although smoothened or keratin-treated hair requires less styling, excessive heat can still weaken the hair over time.

Whenever possible:

• Blow-dry on medium heat.
• Use the lowest effective temperature on styling tools.
• Always apply heat protection before styling.

Reducing heat exposure supports healthier-looking hair and extends the life of your treatment.

8. Protect Hair Between Washes

Daily friction, humidity, and pollution can gradually affect your salon results.

After washing, apply Matrix Mega Smooth Serum through the mid-lengths and ends to smooth flyaways, reduce frizz, and enhance shine. The lightweight formula helps keep hair polished without leaving a greasy finish.

How to Wash Chemically Treated Hair

• Use a sulfate-free shampoo.
• Wash with lukewarm water.
• Gently massage your scalp.
• Condition the mid-lengths and ends.
• Deep-condition once a week.
• Pat hair dry, don't rub.
• Apply a leave-in treatment or heat protectant before styling.
