But what actually happens during these treatments? Are they safe? And most importantly, are they worth the money?
This guide breaks down everything you need to know about hair smoothening—from how it works and what benefits you can expect, to the safest options available and how long the results last. By the end, you’ll have a clearer idea of whether this treatment is right for you.
What Is Hair Smoothening Treatment?
Hair smoothening is a salon treatment designed to temporarily seal your hair cuticle, leaving you with smoother, shinier, and more manageable hair. The exact process and ingredients depend on the type of treatment you choose, but the general idea is the same.
The treatment typically involves applying a smoothening solution to your hair, then using heat styling tools to help the product penetrate deep into the hair shaft. This combination works to flatten the outer layer of each strand, reducing frizz and adding shine.
Most smoothening treatments take around 2 to 3 hours and deliver noticeable results immediately. However, how long those results last—and how dramatic they are—depends on factors like your hair type, lifestyle, and how well you look after your hair afterwards.
A basic hair smoothening treatment typically lasts around 3 months. If you’re after longer-lasting results, treatments like Nanoplastia or Hair Botox can extend that timeframe significantly. These treatments also require minimal touch-ups, which is a bonus if you’ve got a busy schedule.
Benefits of Hair Smoothening Treatment
Here’s what you can expect from a quality smoothening treatment:
1. Reduced Frizz
Frizz is one of the most common hair complaints, especially if you live somewhere humid or polluted. Smoothening treatments tackle this by sealing the hair cuticle and locking in moisture.
The nourishing ingredients in the solution work on the rough outer layer of your hair, flattening each strand and improving its overall appearance. A good treatment will keep your hair sleek and frizz-free even in challenging weather.
2. Enhanced Shine
One of the most immediate and noticeable results of a smoothening treatment is the shine. By sealing the cuticle, the treatment creates a smoother hair surface that reflects light better, giving you that glossy, healthy-looking finish.
Many treatments also include hydrating ingredients that nourish the hair shaft, adding even more lustre to the outer layer.
3. Easier to Manage
If you spend ages detangling or battling knots every morning, a smoothening treatment can be a game-changer. By reducing tangles and taming unruly strands, your hair becomes much easier to style.
You can experiment with different looks without worrying about breakage or spending hours wrestling with your brush. Plus, your hair stays sleek throughout the day, regardless of the weather.
4. Suitable for Most Hair Types
Whether your hair is wavy, curly, damaged, or colour-treated, smoothening treatments can work for you. The gentle yet effective formulas are designed to enhance your natural texture and make hair more manageable across the board.
For damaged or coloured hair, the nourishing ingredients can also help repair and restore health over time.
5. Low Maintenance
Unlike some traditional hair treatments that require strict aftercare routines and regular salon visits, smoothening treatments are relatively low maintenance. Once you’ve had the treatment done, the results typically last for months with just a few simple adjustments to your hair care routine.
Your stylist will give you some basic guidelines to follow, but there’s no need for constant touch-ups or complicated products. This makes it ideal for people with busy lives who still want polished, manageable hair.
Hair Smoothening Treatment Price: What to Expect
The cost of hair smoothening varies quite a bit depending on several factors:
- Hair length – Longer hair requires more product and time, so expect to pay more
- Hair thickness and condition – Very thick or damaged hair may need extra attention
- Salon location – Prices in metro cities tend to be higher than in smaller towns
- Type of treatment – Basic smoothening is cheaper than advanced options like Nanoplastia
- Salon reputation – High-end salons with experienced stylists typically charge premium prices
As a general ballpark:
| Treatment Type | Approximate Price Range (India) |
|---|---|
| Basic Smoothening | ₹2,000 – ₹5,000 |
| Keratin Treatment | ₹4,000 – ₹10,000 |
| Hair Botox | ₹5,000 – ₹12,000 |
| Nanoplastia | ₹8,000 – ₹20,000+ |
These are rough estimates—actual prices can vary widely based on the factors mentioned above. It’s always worth getting a quote from your salon before booking.
Side Effects of Hair Smoothening
While hair smoothening treatments are generally safe when done correctly, there are some potential side effects to be aware of:
- Dryness – Some treatments can strip moisture from the hair if not done properly
- Scalp irritation – Certain chemicals may cause sensitivity or discomfort
- Hair breakage – Excessive heat or harsh formulas can weaken hair over time
- Allergic reactions – Always do a patch test before any chemical treatment
- Formaldehyde exposure – Some older treatments contain formaldehyde, which can be harmful
The good news is that newer treatments—especially those labelled as chemical-free or formaldehyde-free—are designed to minimise these risks. Choosing a reputable salon and asking about the ingredients used can help you avoid potential problems.
Best Hair Smoothening Treatments Without Side Effects
If you’re looking for effective results without the worry of harsh chemicals, here are two of the safest options available:
1. Nanoplastia
Nanoplastia is one of the safest hair treatments you can invest in. Unlike traditional chemical-based options, Nanoplastia uses natural and gentle ingredients that restore hair health while delivering smooth, straight results in a single session.
The treatment uses nanotechnology to penetrate deep into the hair shaft, infusing it with vitamins, proteins, and amino acids. This repairs and seals the hair from within, leaving it healthier and more resilient.
Because it’s chemical-free, Nanoplastia avoids common side effects like dryness, scalp irritation, and breakage.
Pros:
- Lasts up to 75 washes
- Chemical-free and safe
- Suitable for all hair types
- Low maintenance
2. Hair Botox
Hair Botox is another popular smoothening treatment that uses a specialised formula infused with vitamins and proteins. Like other treatments, it takes around 2 to 3 hours and offers smooth, frizz-free results at a relatively affordable price.
What sets Hair Botox apart is that it goes beyond just smoothening. The nourishing and hydrating ingredients repair damaged hair from within, making it an all-in-one solution for frizz, dullness, and manageability issues.
Pros:
- Lasts up to 40 washes
- More affordable than some alternatives
- Reduces frizz and adds shine
- Requires minimal or no touch-ups
How Long Does Hair Smoothening Last?
The longevity of your smoothening treatment depends on several factors:
| Factor | Impact on Results |
|---|---|
| Treatment type | Basic smoothening lasts ~3 months; Nanoplastia can last 4–6 months |
| Hair type | Coarser or curlier hair may see results fade faster |
| Hair care routine | Sulphate-free shampoos and gentle handling extend results |
| Lifestyle | Frequent swimming, sweating, or heat styling can shorten lifespan |
| Touch-ups | Some treatments benefit from occasional maintenance sessions |
Following your stylist’s aftercare advice is the best way to maximise how long your results last.
Post-Treatment Care Tips
To keep your hair looking smooth and healthy for as long as possible:
- Wait before washing – Most stylists recommend waiting 48–72 hours before your first wash
- Use sulphate-free shampoo – Sulphates can strip the treatment from your hair faster
- Avoid heat styling – Give your hair a break from straighteners and curlers for the first week
- Sleep on silk – A silk pillowcase reduces friction and helps maintain smoothness
- Limit hair ties – Avoid tight ponytails or clips that can create creases in the first few days
- Stay out of chlorine – Swimming pools can affect the treatment, especially early on
Is Hair Smoothening Worth It?
If you’re tired of battling frizz, spending ages on styling, or just want hair that looks polished with minimal effort, a smoothening treatment can be a great investment.
The key is choosing the right treatment for your hair type and budget, and making sure you go to a reputable salon that uses quality products. Treatments like Nanoplastia and Hair Botox offer excellent results with fewer risks than older chemical-based options.
That said, it’s always wise to consult with a hair expert before booking. They can assess your hair’s condition and recommend the best option for your specific needs.
Frequently Asked Questions
Is hair smoothening safe for coloured hair?
Yes, most modern treatments are safe for colour-treated hair. In fact, some can help repair damage caused by colouring. However, it’s best to wait a couple of weeks after colouring before getting a smoothening treatment.
Can I do hair smoothening at home?
While DIY kits exist, professional treatments are recommended for best results and safety. Salon stylists have the training and tools to apply the treatment correctly and minimise risks.
Will hair smoothening make my hair straight?
Smoothening reduces frizz and adds manageability, but it doesn’t straighten hair like a rebonding or keratin treatment. Your natural texture will still show through, just in a smoother, more polished way.
How often can I get hair smoothening done?
Most experts recommend waiting until the previous treatment has worn off before getting another one—usually every 3 to 6 months depending on the treatment type.
Final Thoughts
Hair smoothening treatments can be a fantastic solution for anyone dealing with frizzy, unmanageable hair. With options ranging from basic smoothening to advanced treatments like Nanoplastia and Hair Botox, there’s something to suit most hair types and budgets.
The key is doing your research, choosing a safe and effective treatment, and following proper aftercare to make your results last. If you’re unsure which option is right for you, a quick consultation with a trusted hair professional can point you in the right direction.
