Bio Sleek

What is Bio Sleek?
Bio Sleek is an organic straightening treatment that permanently straightens curly or wavy hair. It’s formaldehyde-free, fume-free, and delivers long-lasting shine and softness.

Is Bio Sleek safe for bleached or colored hair?
Yes, when combined with Nano Silky, Bio Sleek can be used on non-damaged bleached hair or colored hair from level 8 and up. This combo protects the hair while delivering straightening results.

How long do Bio Sleek results last?
Bio Sleek is a permanent straightening treatment. Results last until new hair grows and require root touch-ups every 6–12 months.

Can I wash my hair right after Bio Sleek?
Yes! Bio Sleek is 100% washable before flat ironing, so you can cleanse the hair, blow dry, and finish the treatment the same day.

Can I use Bio Sleek if I'm pregnant or breastfeeding?
Yes. Bio Sleek is a natural, safe formula but always check with your doctor if unsure.

What if some curls remain after I wash my hair?
Just pass a flat iron through the section once. Bio Sleek allows one-time correction with heat after the first wash if needed.

Can I use Bio Sleek if I have allergies?
Bio Sleek is a natural, formaldehyde-free formula. However, if you have allergies or sensitivities, we recommend testing a small section of hair behind the ear before applying it fully. For extra safety, consult your doctor.

Step 1: Wash
Wash twice with Clarifying Shampoo. Rinse and dry 100%.

Step 2: Apply Treatment
Apply Bio Sleek section by section, ¼ inch from the root.
Leave on for 60 minutes with heat (or 90 for coarse/curly hair).

Step 3: Rinse
Rinse thoroughly with water.
For damaged hair: apply conditioner or a mask before styling.

Step 4: Blow Dry & Flat Iron
Blow dry completely.

Flat iron each section 4–6 times using a high-heat iron (up to 480°F / 250°C) until the hair is straight, smooth, and shiny.
