Firm scalp manipulations should not be used prior to hair coloring because they can lead to scalp irritation, which could be worsened by the chemicals in hair coloring products.
Never use firm scalp manipulations when shampoo is to be followed by hair coloring. Firm scalp manipulations can lead to irritation of the scalp, which might be exacerbated by the chemicals used in hair coloring processes. It is critical to treat the scalp and hair gently before chemical treatments to prevent discomfort and potential damage. When a client is preparing for hair coloring, the stylist should opt for a gentle shampoo and avoid vigorous scrubbing. For other services such as hair cutting, hair styling, or hair conditioning, firm scalp manipulations are less likely to cause issues, but it's always important to consider the client's scalp condition and preferences.
