Hair Smoothening For Curly Hair: What You Should Expect

Curly hair is beautiful, bold, and full of personality. But it can also be unpredictable, especially when it comes to frizz, tangles, and daily styling. If you’ve ever wished for smoother, more manageable curls—or just wanted a break from constant straightening tools—you might have considered hair smoothening.

But is smoothening a good option for curly hair? The short answer is: Yes, it can be—if you know what to expect. Hair smoothening doesn't eliminate your curls completely unless you opt for stronger formulas. Instead, it softens the curl pattern, reduces frizz, and gives your hair a sleeker, shinier look.

In this article, we’ll explain what hair smoothening is, how it works on curly hair, the results you can expect, and how to take care of your hair afterward to keep it healthy and beautiful.

What Is Hair Smoothening?

Hair smoothening is a semi-permanent treatment that relaxes the natural bonds in your hair, making it smoother, shinier, and easier to manage. It uses gentle chemicals—often amino acids, cysteine, or keratin-based formulas—followed by heat to seal the treatment into the hair strands.

It’s not the same as hair rebonding, which completely straightens hair by changing its structure. Smoothening is less aggressive and gives a more natural finish.

Is It Suitable for Curly Hair?

Yes, hair smoothening can be done on curly hair, but the results will vary depending on your hair type and curl pattern. Here’s how different types of curls may respond:

• Loose curls or waves may become almost straight with a smooth texture.
• Medium curls will likely loosen into soft waves or large curls.
• Tight or coily curls may become more manageable but may not become fully straight without stronger treatments.

If your goal is not to completely straighten your curls, but to soften them and reduce frizz, then hair smoothening is a great option.

Benefits of Smoothening Curly Hair

There are several reasons why curly-haired individuals opt for hair smoothening. Here are the biggest advantages:

1. Frizz Reduction : Smoothening controls frizz by sealing the hair cuticle, leaving curls looking more defined, shinier, and healthier.

2. Easier Styling : After smoothening, you’ll spend less time detangling, blow-drying, or flat ironing. Your hair becomes easier to comb and style daily.

3. Soft and Silky Feel : The treatment nourishes the hair shaft, resulting in a silky texture that feels smooth to the touch.

4. More Polished Appearance : Your curls will look more uniform, and your hair will appear healthier and glossier.

5. Temporary Commitment : Since smoothening is semi-permanent, your natural curls will gradually return, giving you the flexibility to switch styles over time.

What to Expect During the Treatment

If you’re getting smoothening done for the first time, here’s what the typical salon process looks like:

Step 1: Consultation
The stylist examines your hair texture, thickness, and overall health. If your hair is damaged or very dry, they may recommend a few conditioning treatments first.

Step 2: Clarifying Wash
Your hair is washed with a clarifying shampoo to remove any product buildup and open the hair cuticles.

Step 3: Application of Smoothening Cream
A smoothening formula is applied section by section, focusing on evenly coating all strands. This may take 30–45 minutes.

Step 4: Rinse and Blow-Dry
After letting the cream sit for the required time, it’s rinsed out. Your hair is then blow-dried to prepare for heat sealing.

Step 5: Flat Ironing
Using a professional-grade flat iron, your stylist seals the treatment into the hair. This is where most of the smoothening happens and helps the hair maintain its new shape.

Step 6: Final Rinse (If Needed)
Some treatments may require a follow-up rinse or application of a neutralizer.

Time Needed:

The entire process usually takes 3 to 4 hours, depending on hair length and curl type.

What Results Should You Expect?

It’s important to have realistic expectations when smoothening curly hair. The goal is to make the hair smoother and less frizzy—not necessarily bone-straight.

Here’s what you can typically expect:

• Loose Curls or Wavy Hair: Will appear straight or lightly wavy after treatment.
• Medium Curls: Will be visibly relaxed with soft waves or large curls.
• Tight Coils: Will become looser and more manageable but likely remain curly unless a more intense treatment is used.

Your hair will look glossier, feel softer, and be far easier to handle in humid or dry conditions. The results usually last 3 to 6 months, depending on the treatment and how well you maintain your hair.

Aftercare Tips for Smoothened Curly Hair

Caring for your hair after the treatment is essential to maintain its smooth and healthy appearance.

1. Do Not Wash for 3 Days
Avoid washing your hair for at least 72 hours after the treatment. This allows the smoothening cream to fully settle.

2. Use Sulfate-Free Shampoo
Regular shampoos with sulfates can strip the treatment. Always use a mild, sulfate-free shampoo and conditioner to maintain the smooth texture.

3. Avoid Heat Styling
Minimize the use of blow dryers, curling irons, and straighteners. Your hair should now need much less styling anyway.

4. Regular Conditioning
Use a hydrating hair mask once a week to nourish your curls and maintain elasticity and moisture.

5. No Tying or Braiding Initially
Avoid tying your hair or tucking it behind your ears for the first few days to prevent dents or creases.

Possible Side Effects (and How to Avoid Them)

Hair smoothening is generally safe, especially when done by professionals, but here are a few things to keep in mind:

• Dryness or Breakage: Use deep conditioners and avoid harsh treatments like bleaching right after smoothening.
• Scalp Sensitivity: If you have a sensitive scalp, inform your stylist beforehand and ask for a milder product.
• Chemical Smell: Some products may have a strong odor. Well-ventilated salons and formaldehyde-free options are best.

Overall, risks are minimal when you follow expert guidance and choose a reputable salon.

Is It Worth It for Curly Hair?

Yes, especially if you’re looking for a way to tame frizz, reduce volume, or make your curls easier to style without completely losing their texture. Smoothening is a fantastic in-between treatment—not as aggressive as rebonding, but more effective than a basic keratin treatment for curl softening.

Many people with curls appreciate the freedom it gives—whether it’s skipping the flat iron or simply enjoying soft, tangle-free hair on a daily basis.

Final Thoughts

Hair smoothening for curly hair can be a great way to enjoy smoother, more manageable locks without permanently altering your natural texture. It’s a gentle, semi-permanent solution that offers visible transformation while giving you the option to return to your natural curls over time.

By knowing what to expect and following the right aftercare routine, you can enjoy the best of both worlds—sleek, shiny hair when you want it, and your lovely curls when you’re ready to embrace them again.
