12 Best Hair Relaxers Tested by Experts

If you’re dreaming of silky-smooth, frizz-free, manageable hair, the right hair relaxer can feel like magic. But not all relaxers are created equal—some nourish and condition, while others can be harsh without proper care. That’s why choosing the best formula matters. The good news? We’ve done the work for you. Today, we’re breaking down the 12 best hair relaxers, tested and approved by professional stylists, dermatologists, and textured-hair experts.

Whether you want long-lasting sleekness, gentle straightening treatments, or effective chemical hair care solutions for coils and curls, this expert guide has you covered.

 

 

What Are Hair Relaxers and How Do They Work?

Hair relaxers are chemical straightening treatments designed to permanently loosen curl patterns and reduce frizz. These products work by breaking the disulfide bonds within the hair shaft, allowing strands to reshape into a straighter form.

Why choose a relaxer?

  • Long-lasting smoothness

  • Low-maintenance styling

  • Easier detangling

  • Frizz control in humid weather

If you love sleek ponytails, straight blowouts, or polished looks that pair beautifully with everything from minimalist outfits to formal wear, relaxers offer a dependable foundation.

 

 

Types of Hair Relaxers

Before diving into the best picks, it’s important to understand the main categories.

1. Lye Relaxers

These contain sodium hydroxide and work quickly. They’re often used in salons for fast, predictable results.

Best for: Coarse, thick, or highly textured hair.

2. No-Lye Relaxers

These use calcium hydroxide or guanidine carbonate, making them gentler on sensitive scalps.

Best for: Beginners or individuals with scalp sensitivity.

3. Thio Relaxers

Ammonium thioglycolate formulas similar to Japanese straightening treatments.

Best for: Looser curls or waves.

4. Natural or Botanical Relaxers

These do not chemically break bonds but smooth hair for temporary manageability.

Best for: Mild, non-permanent smoothing.

Expert Safety Tips for Chemical Hair Care

Relaxers are effective, but they must be used with care. Experts recommend:

  • Do a patch test 48 hours prior

  • Never scratch your scalp before relaxing

  • Protect hairline with petroleum jelly

  • Do not overlap relaxers on previously processed hair

  • Rinse thoroughly with neutralizing shampoo

  • Deep condition immediately after

How Often Should You Relax Your Hair?

Most experts recommend every 8–12 weeks depending on your new growth. Over-processing can lead to breakage, thinning, and scalp irritation—so timing is key.

 

 

After-Relaxer Hair Care Routine (Stylist Approved)

To maintain smooth, strong, healthy hair:

1. Moisturize regularly.

Use leave-ins and hair milks to maintain softness.

2. Deep-condition weekly.

Choose masks enriched with keratin, proteins, and natural oils.

3. Avoid excessive heat.

Your hair is more fragile post-processing.

4. Sleep on satin.

A satin pillowcase keeps friction low and prevents dryness.

5. Trim every 8–10 weeks.

Prevents split ends and keeps relaxed hair looking sleek and polished.

 

 

Common Myths About Hair Relaxers

Myth 1: Relaxers completely ruin your hair.

Not true—damage only occurs when relaxers are misused or applied too frequently.

Myth 2: All relaxers work the same.

They differ in strength, ingredients, and purpose.

Myth 3: Natural hair can’t go back once relaxed.

Relaxing is permanent, but new growth comes in natural—allowing for transitions.

 

 

Pairing Relaxed Hair With Fashion: The Style Advantage

Relaxed hair often complements a clean, elevated wardrobe. Sleek strands look amazing with:

  • Structured blazers

  • Minimalist jewelry

  • Silk tops

  • Statement dresses

  • Streetwear-chic looks
