Common Questions

What distinguishes Keratin Protein Gold 2.4 from other smoothing treatments in the range?

The 2.4 Gold version is our maximum-strength smoothing reconstructor. It is specifically engineered for “resistant” hair types—including coarse, thick, and highly textured hair—that require more intensive curl reduction. The “Gold” designation refers to the ultra-refined 24K-Shine technology, which coats the hair in a reflective, luxurious gloss while providing a stronger straightening effect than standard protein treatments.

How does the "Gold-Protein Complex" work to transform resistant hair textures?

The Keratin Protein Gold 2.5 treatment utilizes a high-density molecular blend of hydrolyzed keratin and collagen. Because resistant hair has a more compact cuticle layer, this formula uses a specialized delivery system to penetrate deep into the cortex. Once inside, it realigns the hair’s sulfur bonds and “fills” the fiber with gold-standard nutrients, resulting in a 90-100% reduction in frizz and curl without compromising the hair’s natural bounce.

Is Keratin Protein Gold 2.4 safe for clients who prioritize a formaldehyde-free experience?

Absolutely. Like all products in the PRO-TECHS 0+ system, the Gold 2.4 is 100% formaldehyde-free. We utilize advanced glyoxylic acid derivatives and organic acids to achieve the straightening effect. This ensures a safe, smoke-free, and comfortable environment for both the stylist and the client, providing high-performance results without the health risks associated with traditional Brazilian keratin treatments.

What is the expected longevity of the Gold 2.4 treatment, and how does it fade?

Due to its high-concentration formula, the Gold 2.4 professional treatment offers superior durability, typically lasting between 4 to 6 months. Unlike chemical relaxers that leave a permanent “line of regrowth,” this treatment fades gradually and naturally over time. The hair remains manageable and soft, with the frizz-reduction benefits lasting until the treatment is naturally washed away or the hair grows out.

Which flat-iron technique is recommended to activate the "Gold Shine" effect?

To fully activate the gold-standard shine and straightening agents, the flat-ironing stage is critical. For healthy, resistant hair, we recommend using a high-quality titanium iron set to 230°C (450°F). Stylists should work with thin, transparent sections, passing the iron 6 to 10 times from root to mid-shaft, and slightly fewer times on the ends. This thermal process vitrifies the protein layer, sealing the “Gold” pigments into the cuticle for that signature high-gloss finish.
