I understand what you are saying, that people other than professionals can use professional products, but I am afraid I do have to say that, as a professional with 10 years experience, years of training and 8 years of salon ownership under my belt, I am slightly offended by this statement. The use of professional products may not be 'rocket science' but it is a skill/artform backed up with specific training to enable safe and effective use of the products. I may have read this incorrectly, but to me it comes across in the same manner in which a client might say whilst I am applying her nail enancements 'oh this is so easy to do isn't it, I think I will look into being a nail tech cos can't be hard'... this is said many a time by clients opposite me. It doesn't offend me because I take flattery in the fact I must be making it look easy. I giggle a little secretly inside and think 'ok love...' because I KNOW it may look easy but it is a skill for which I am proud to have trained in and become very knowledgable and experienced in over the years. I don't agree that these professional products should be widely available for general use - they were created and developed for professional use for good reasons. I do agree that general use of a professional product will always be there - people always find a way to put it out there to non-professionals but I certainly don't condone it. I would be offended if a client told me they went out and bought a Shellac system to do at home - not because I lose money but because it undermines the job that I do.
