2. Always mix the booster with a Majirel baSistint, never with oxidant alone.
3. Use max a quarter tube booster to three quarters of Majirel colour cream.
4. Add the suitable L'Oréal ProfesSisional oxidant in the prescribed ratio.
5. Apply the mixture to the hair, allow processing time, then rinse thoroughly.

After colouring, your hair needs extra care. Absolut Repair Molecular Shampoo helps strengthen your hair post-colour and keeps the colour vibrant for longer.

The colour penetrates deeply into the hair shaft and doesn't fade quickly. This happens because ammonia temporarily opens the hair cuticles, allowing colour molecules to enter and lock in. Once inside, they form larger coloured particles that last.

The formula also contains fatty acids that coat the hair shaft during colouring, leaving a smoother feel after rinsing. The ammonia smell is noticeably less than classic colour products, making colouring more pleasant. For those wanting cooler coverage of grey hair or neutralising undertones, this is a reliable choice. Find the full range at L'Oréal ProfesSisional.

Your choice depends on what you want to correct or enhance. Majirel Booster - 60mls come in neutral and colour-targeted variants, each with a clear purpose.

Blue and Violine are for those wanting to counter warm yellow or orange hues. Your hair will have a cooler, ashier finish. Copper and Red are for adding extra warmth or vibrancy to brown or dark tones. Contrast Base is used as a base for strong contrasting colour effects.

Compared to standard Majirel baSistints, the boosters are more concentrated and thus more powerful in small amounts. If you only want colour without correction, a separate Majirel tint is the better choice. For precise mixing ratios, always follow L'Oréal's technical guide to avoid results that are too dark or muddy, especially on porous or very grey hair.

No, the booster should always be combined with a Majirel baSistint and an oxidant. Using only oxidant will not give good results. The correct ratio is a quarter tube booster to three quarters Majirel colour cream, plus the matching oxidant.

For yellow undertones, choose the Blue variant. If you have an orange tint, Violine works best. Both variants were developed to cool warm tones and deliver a ashier finish, even when covering grey hair.

For more than fifty per cent grey hair, adjust the dosage. Grey hair absorbs colour differently from pigmented hair. Use slightly less booster than the maximum amount and watch processing time carefully. This avoids results that are too cool or too dark.
