Bio Sleek™ vs Nano Silky: Which Treatment Should You Choose?
Both treatments improve the hair, but each one is designed for a different result.
Bio Sleek™ Straightening Treatment
Best for straightening the hair.
✔ Straighter hair
✔ Curl reduction
✔ Smoother, flatter result
✔ More control over curly, coarse, or resistant hair
✔ Long-lasting straightening results
Nano Silky Smoothing Treatment™
Best for smoothing, frizz control, softness, shine, and natural movement
✔ Less frizz
✔ More softness and shine
✔ Easier blow-drying and styling
✔ Smoother, healthier-looking hair
✔ Natural movement
✔ Not fully straight hair
When to Combine Nano Silky + Bio Sleek
Best for straightening bleached hair.
When the client has bleached hair and wants a straighter result, the best option is often to combine Bio Sleek with Nano Silky.
This helps create a straighter, smoother result while keeping the hair softer and more protected.
Best for clients with:
✔ Bleached hair
✔ Lightened blonde hair
✔ More delicate hair that still wants straightening
✔ Hair that needs both straightening + softness
Professional note:
For bleached hair, the combination is usually 90% Bio Sleek + 10% Nano Silky, depending on the hair condition and the stylist’s evaluation.
How Bio Sleek™ Works
Bio Sleek™ Straightening Treatment is an organic amino-acid-based straightening treatment designed for professional hairstylists.
The treatment works with heat to help reduce curl pattern, control frizz, and create long-lasting straight, smooth, shiny hair. Once sealed with heat, the treated hair becomes easier to blow-dry, style, and maintain.
Bio Sleek is a 100% washable treatment, meaning the product is rinsed from the hair before blow-drying and flat ironing. This creates a cleaner, more comfortable salon experience while still delivering professional straightening results.
What Our Customers Are Saying
Bio Sleek is a game-changer for my salon. It offers permanent straightening without the fumes and smoke that other treatments cause. I can go back and correct any missed spots after the first wash, which is a huge benefit for maintaining quality results. Plus, knowing it’s safe for kids and pregnant women makes it the go-to treatment for everyone!
As a salon owner, my stylists enjoy working with Bio Sleek because it’s easy to apply and delivers incredible results. Our clients love that it’s organic and free of harsh chemicals like formaldehyde. The fact that it's washable before flat ironing ensures that they can provide perfect results every time. The feedback from clients has been fantastic – smoother, shinier hair that lasts for months!
I have naturally curly hair, and Bio Sleek straightened it beautifully. It’s been months, and my hair is still sleek and manageable. I came back just to straighten my roots as they grew out, and the results are just as amazing every time!
After my initial Bio Sleek treatment, my hair stayed perfectly straight for months. Now, I only come back to have my roots touched up as they grow in. The treatment keeps my hair smooth, shiny, and frizz-free – I’ve never experienced anything like it!
