Frequently Asked Questions

Why is an acidic haircare product beneficial?

Healthy hair maintains an acidic pH of 4.5 to 5.5. Daily exposure to alkaline sources such as water and chlorine can cause damage. Acidic products help restore and balance that pH level.

How much product should I apply?

The Acidic Bonding Concentrate System is concentrated. Start with a dime-sized amount and adjust based on your hair’s thickness and length.

Is this system suitable for color-treated hair?

Yes, the Acidic Bonding Concentrate is designed to be safe for color-treated hair.

How does it differ from other bonding products?

Unlike traditional bonding treatments that require in-salon applications, Acidic Bonding Concentrate products contain Citric Acid for at-home, time-saving strengthening solutions.

How can I prevent bonding or protein overload?

Using solely strengthening products risks protein overload. Our system balances strengthening and moisture for healthy, resilient hair.
