I did a new client last week and used 12.0 on her roots. Shes complained today saying that they are to warm. I myself thought it was to warm, it went more like a 12.3. She has now told me she thinks the salon she previously went to used a 9. If I cover with a 9 will that work? Should i use 9.0 or 9.1?
