Wash your hair with a neutral shampoo three times, making sure the last time the shampoo acts for 10 minutes. Then, dry it completely and divide it into 4 sections, protecting your clothes with a cape or towel.

Prepare the mixture when you are ready to apply it. In a plastic container, combine step 1 and step 2 in equal proportions. Do not use them separately, as they work best when mixed together. Shake vigorously for 1 minute, making sure to achieve a homogeneous mixture.

Apply the mixture to your hair, distributing it evenly over the desired area. Leave it on for 30 minutes, preferably covering your hair with a thermal cap. After this time, remove the thermal cap and let it sit for an additional 5 minutes.

Rinse thoroughly with water for at least 5 minutes. Then apply the neutral shampoo twice, leaving it to act for 3 to 5 minutes between each application. Rinse well and dry your hair completely. If you are not satisfied with the result, you can repeat the process (steps 2 and 3).
