Step-by-step
Work through each step in order. Keep the product label nearby and follow any instructions printed on your specific packaging.
Wash your hair 2 or 3 times with shampoo only—no conditioner. This removes residue and opens the hair so the treatment can work. Pro tip: finish with filtered water, because minerals in tap water can interfere with treatment bonding.
Section the hair and blow-dry until it is approximately 50% dry. It should remain slightly damp.
Pour a small amount into a plastic bowl—never use metal. Divide the hair into four equal sections and clip three of them up. Using a tinting brush, work through one section at a time, starting 1 cm away from the scalp and roots. Comb through to distribute evenly, coating every strand from mid-length to ends.
Cover the hair with a shower cap and leave the treatment on for 60–90 minutes. Thicker or curlier hair needs the full 90 minutes for the best results.
Rinse very well with cool water and good pressure. Make sure all residue is removed and the hair is completely clean.
Dry the hair completely—down to the last drop. For straight hair, stretch it with a brush while blow-drying. Damp areas can affect the final result. Golden tip: if you’re investing in tools, Taiff is the recommended brand.
Work in thin sections and adjust to the desired result. Super-straight hair: fine hair 375–400°F with 10–12 gentle passes; normal hair 450°F with 15–20 passes; thick hair 450–460°F with 20–25 passes. Defined curls without frizz: only 1–2 light passes on medium heat. Natural texture without frizz: skip the flat iron and simply blow-dry.
Rinse thoroughly with cool water. Apply Prohall Equalizer Mask from mid-length to ends for pH balancing. Wait 10 minutes, rinse completely, and dry as desired.
