Our Full Cover Anti-Thinning Shampoo is designed to soften the hardest part of your haircare routine. Here’s how it works:

• Aminexil: Strengthens your hair right at the roots by boosting scalp circulation, giving you a solid foundation for thicker hair.
• Biotin: Supercharges keratin production, making your hair more resilient to hard water's drying effects, keeping your strands strong and less prone to breakage.
• Astaxanthin: Shields your hair follicles from oxidative stress caused by hard water minerals, helping to keep your hair looking and feeling healthier.
• Klean Complex: Our unique blend neutralizes those stubborn hard water minerals like calcium and magnesium, stopping them from clinging to your hair. This keeps your hair free from buildup, so it stays soft, smooth, and full.

In our clinical study, 23 participants used the Hello Klean Anti-Thinning Shampoo consistently over 84 days. The goal was to evaluate its effectiveness in reducing hair loss and improving hair density.

Participants used the shampoo every two days, and we measured the results at various intervals. By the end of the study, the results were clear:

• Hair Loss Reduction: After 84 days, there was a significant 20% reduction in hair loss compared to the beginning of the trial.
• Increased Hair Density: Local hair density increased by 13.73%, showing a noticeable improvement in hair thickness and coverage.

These findings confirm that our Anti-Thinning Shampoo not only helps reduce hair loss but also promotes fuller, healthier hair with continued use.

It’s gentle enough for daily use and works continuously to protect your hair from hard water damage.
