Straightening Shampoo Voltage Liso Keratina Keratin 500 ml

This shampoo is primarily designed to preserve and extend the effects of professional straightening treatments. While it promotes smoothness and reduces frizz, it is not a standalone straightening product for significantly curly or coarse hair.

For best results in maintaining straightening treatments, it is recommended to use this shampoo 2-3 times per week. On other wash days, use a gentle, sulfate-free shampoo if needed.

Yes, the formula is generally safe for color-treated hair and is designed to help maintain the vibrancy and integrity of treated hair, including color.

'Liso' is Portuguese/Spanish for 'smooth' or 'straight', and 'Keratina' refers to keratin, the key protein ingredient in the shampoo.

The keratin helps to penetrate the hair shaft, repairing damage, filling in gaps in the cuticle, strengthening the hair fibers, and reducing frizz for a smoother appearance.

This shampoo is specifically formulated with ingredients like keratin and other smoothing agents to prolong straightening treatment effects and combat frizz, whereas regular shampoos focus on basic cleansing.

Usage frequency and hair length will affect longevity. For someone using it 2-3 times a week on shoulder-length hair, a 500ml bottle could last approximately 2-3 months.

Ensure you are rinsing the shampoo out completely. Follow with a compatible conditioner and consider air-drying or using a heat protectant if blow-drying.

Verify that you are using the shampoo consistently and not alternating with harsh or clarifying shampoos. Ensure your original straightening treatment was applied correctly.

You may be using too much product. Try reducing the amount used or ensure thorough rinsing. Consider if you have very fine hair, which may react differently.

Discontinue use if irritation persists. Rinse thoroughly after shampooing and consider if you have sensitive skin. Consult a professional if symptoms persist.
