To get the most out of Keratin Complex products:
- Always follow the instructions on the packaging.
- Alternate between mask and conditioner based on your needs: use the mask 1-2 times a week, conditioner after every shampoo.
- Don’t use too much product: the right amount prevents weighing hair down.
- For anti-yellow products, monitor the processing time to avoid unwanted tones.
- If dealing with dandruff, combine mask and serum for a more complete treatment.
Avoid using products unsuitable for your hair type (for example, volumizers on already thick hair or anti-yellow products on dark hair). Never skip thorough rinsing, essential to avoid residue.
