If you’re looking for a way to smooth, strengthen, and revive your hair, you’ve probably come across both Hair Botox and keratin treatments. While both promise to tame frizz and improve the look of your hair, they work in completely different ways. But which one is better?

At Salon No. 100, we help clients choose the best treatment for their hair type and lifestyle. This guide will break down how Hair Botox and keratin differ, who they’re best suited for, and which one might be the better choice for you.

What Is Hair Botox and What Does It Do?

Hair Botox is a deep-conditioning treatment designed to repair damage, smooth frizz, and restore moisture. Unlike keratin treatments, it does not contain formaldehyde or change the structure of your hair.

Instead, it works by coating each strand with hydrating ingredients like:

Amino acids – Strengthen the hair from within.
Collagen and proteins – Improve elasticity and reduce breakage.
Essential oils and antioxidants – Restore shine and softness.

This makes Hair Botox ideal for dry, damaged, or frizzy hair that needs extra nourishment without being chemically altered. It’s especially great for fine or colour-treated hair, as it won’t weigh it down or cause further damage.

What Is a Keratin Treatment and How Does It Work?

A keratin treatment is a chemical smoothing treatment that straightens hair while reducing frizz. It works by applying a keratin-based formula to the hair, which is then sealed in with heat. The result? Silky, straight, and smooth hair that lasts for months.

Key Features of a Keratin Treatment

Long-lasting straightening effect (up to six months)
Reduces frizz and adds shine
Contains formaldehyde or other chemicals to change hair texture
Requires heat to bond the product to the hair

While keratin treatments work well for thick, curly, or unruly hair, they may not be the best choice for fine or already damaged hair due to the chemical processing involved.

Hair Botox vs. Keratin: Which One Is Better?

Now that we’ve broken down what each treatment does, let’s compare them side by side.

1. Do They Change Your Natural Hair Texture?

Hair Botox: No. It smooths and nourishes but won’t straighten your natural waves or curls.
Keratin Treatment: Yes. It chemically alters the structure of your hair, making it straight and sleek.

2. Which One Is Safer for Your Hair?

Hair Botox: Completely safe, as it contains no harsh chemicals.
Keratin Treatment: Effective but may contain formaldehyde, which some people prefer to avoid.

3. How Long Do They Last?

Hair Botox: Around six to eight weeks, depending on hair care.
Keratin Treatment: Up to four to six months with proper maintenance.

4. Which One Is Better for Coloured or Bleached Hair?

Hair Botox: Great for restoring moisture and repairing damaged hair.
Keratin Treatment: Can be used on coloured hair but requires extra care to prevent further damage.

5. How Do They Feel on the Hair?

Hair Botox: Leaves hair feeling soft, bouncy, and natural.
Keratin Treatment: Leaves hair straight, smooth, and sleek, sometimes reducing volume.

If you want to keep your natural texture but fight frizz and dryness, Hair Botox is the better choice. If you want pin-straight hair with long-lasting results, a keratin treatment is the way to go.

Who Should Choose Hair Botox?

Hair Botox is best for those who:

Have dry, damaged, or colour-treated hair
Want to reduce frizz but keep their natural waves or curls
Prefer a chemical-free treatment
Need extra hydration and repair

It’s an excellent damage-repair treatment that makes hair softer, shinier, and healthier without altering its structure.

Who Should Choose a Keratin Treatment?

A keratin treatment is better suited for those who:

Have thick, curly, or frizzy hair and want it straighter
Want long-lasting smoothness
Are happy with a chemical treatment
Don’t mind the extra maintenance required to keep it looking fresh

If your goal is sleek, straight hair that requires minimal styling, keratin is the best choice.

FAQs

Will Hair Botox Make My Hair Straighter?

No, Hair Botox does not straighten hair. It reduces frizz and makes hair more manageable, but your natural waves or curls will remain.

Can I Get a Keratin Treatment on Fine Hair?

It depends. Keratin can make fine hair look flat or limp, so it’s better suited for those with thicker, coarser textures.

Does Hair Botox Contain Formaldehyde?

No! Hair Botox is free from harsh chemicals and works by coating the hair with nourishing ingredients.

How Often Can I Get Hair Botox or a Keratin Treatment?

Hair Botox: Every six to eight weeks to maintain smoothness and hydration.
Keratin Treatment: Every four to six months, depending on hair growth and washing routine.

Which One Requires More Maintenance?

Keratin treatments require special sulfate-free shampoos and a strict aftercare routine to keep them looking fresh. Hair Botox is easier to maintain, requiring hydrating shampoos and masks to prolong results.

Final Thoughts: Which One Should You Choose?

At Salon No. 100, we love both treatments for different reasons. If your hair is dry, brittle, or frizzy but you want to keep your natural waves, Hair Botox is the better choice. If you want sleek, pin-straight hair that lasts for months, keratin is the way to go.Not sure which one is right for you?
