What's important to know is whether the virgin level is a 4 OR a 5. What volume were you using for each one? Also, what is the texture of the hair like? Coarse or fine? If it's coarse, I find that 30 or 40 vol is needed when 20 vol would have easily lifted it on someone with finer hair. If you're getting an RR or RV tone that you wouldn't expect, then most likely there is something in their counteracting what you're putting in. A full consultation is very necessary. |
