DIY vs. Salon Hair Smoothening: What Actually Works?

DIY vs. Salon Hair Smoothening: What Actually Works?

Hair smoothening has become one of the most popular treatments for achieving sleek, frizz-free, and shiny hair. Whether you're dealing with waves, curls, or unmanageable texture, smoothening can dramatically improve how your hair looks and feels. But the real question is—should you do it yourself at home or visit a salon?

With an increasing number of at-home smoothening kits available on the market, many people are tempted to try the DIY route. It seems convenient and cost-effective, but is it truly as effective or safe as getting your hair smoothened at a professional salon?

In this article, we’ll break down the key differences between DIY and salon hair smoothening, compare the results, and help you understand which option may be right for you.

What Is Hair Smoothening?

Hair smoothening is a semi-permanent chemical treatment that softens your natural texture, reduces frizz, and makes hair look sleeker and shinier. It typically involves applying a smoothening cream (such as keratin, cysteine, or a relaxer), followed by flat ironing to lock in the effects.

Unlike hair rebonding, which makes hair permanently straight, smoothening gives a more natural finish—your hair becomes easier to manage without appearing overly processed.

DIY Hair Smoothening: What to Expect

Pros of DIY Smoothening

1. Cost-Effective
   DIY kits are far more affordable than salon services. A good-quality home kit may cost anywhere from $15 to $50, compared to $100 to $300 at a salon.

2. Convenience
   You can do it on your schedule, in the comfort of your own home, without waiting for appointments.

3. Control Over Products
   You know exactly what’s going on your hair. Many DIY kits claim to be free of harsh chemicals like formaldehyde.

4. Ideal for Minor Frizz
   If your hair is only slightly frizzy or wavy and doesn’t require strong chemical restructuring, a DIY kit may offer noticeable improvement.

Cons of DIY Smoothening

1. Risk of Mistakes
   Smoothening requires precision. Uneven application, wrong timing, or improper heat use can lead to poor results or even damage.

2. Not Suitable for All Hair Types
   If you have thick, coarse, curly, or previously treated hair, home kits may not be strong enough to make a difference.

3. No Customization
   DIY kits are one-size-fits-all. A professional stylist can assess your hair type and adjust the treatment accordingly.

4. Results May Not Last Long
   Most at-home kits offer results that last 2–4 weeks, whereas salon smoothening can last 3–6 months.

Salon Hair Smoothening: What to Expect

Pros of Salon Smoothening

1. Professional Expertise
   A trained stylist knows how to handle various hair types and conditions. They can adjust product strength and heat levels to suit your specific needs.

2. Longer-Lasting Results
   Salon treatments typically last longer—anywhere from 3 to 6 months, depending on your hair type and aftercare routine.

3. Consistent and Even Application
   Professionals apply products evenly and carefully flat iron each section, ensuring uniform smoothness and shine.

4. Custom Solutions
   Salons offer different types of smoothening treatments—like keratin, cysteine, or Botox treatments—based on your hair’s condition and goals.

5. Better Finish and Shine
   Salon treatments use higher-quality tools and products that can deliver more dramatic and polished results.

Cons of Salon Smoothening

1. Higher Cost
   Salon treatments can be expensive, often ranging from $100 to $300 or more depending on the salon and hair length.

2. Time-Consuming
   The entire process can take 3 to 5 hours, depending on hair type and thickness.

3. Chemical Exposure
   Some salon treatments may contain chemicals like formaldehyde, which can cause irritation if not handled correctly. However, many salons now offer formaldehyde-free options.

Side-by-Side Comparison

So, What Actually Works Better?

If You Want Quick, Temporary Results…

DIY smoothening can work if your hair is only mildly frizzy and you’re looking for short-term manageability. It’s a great option for experimenting or preparing for a one-time event.

If You Want Long-Lasting, Salon-Quality Results…

Salon smoothening offers more noticeable, long-lasting results. It’s ideal for anyone with thick, curly, unmanageable, or chemically treated hair. A professional can analyze your hair condition and apply a treatment that minimizes risk and enhances results.

Things to Keep in Mind for Either Option

Regardless of which method you choose, aftercare is essential to maintain the smoothened look:

• Use sulfate-free shampoos and conditioners

• Avoid washing your hair for 72 hours after treatment

• Apply a deep conditioning mask once a week

• Stay away from chlorinated pools and salty ocean water

• Avoid frequent use of heat styling tools

Expert Tips for Best Results

• Always perform a strand test if using DIY kits.

• If your hair is colored or chemically treated, consult a professional before applying any product.

• Hydrate and nourish your hair regularly to avoid dryness or breakage.

• Avoid doing smoothening too often (wait at least 4–6 months between treatments).

• Consider a keratin or cysteine-based treatment for a gentler, formaldehyde-free experience.

Final Thoughts

Both DIY and salon hair smoothening have their place, depending on your goals, hair type, budget, and comfort level. If you’re confident in your application skills and just want a temporary solution for mild frizz, DIY kits can be a convenient choice. However, for long-term results, better finish, and minimal risk, nothing beats a professional salon treatment.

Ultimately, smooth, sleek, and shiny hair is within your reach—you just have to choose the path that fits your lifestyle and needs best.
