Can hair treatments affect results?
We have not found any influence from cosmetics and shampoo but there may be occasions when this should be considered (example: hair modelling where the hair is constantly being styled). Recent alcohol application to the scalp for head lice will also not affect the results. Our experience in this field would allow us to offer constructive advice on such occasions.
