It has come to my attention through industry contacts that it seems clients are having reactions to colour even if they have had colour for many years without problems. We have never before had the corona virus to contend with and we must be extra vigilant to protect our clients.
It would appear that the corona virus and the vaccine may possibly upset the body and its sensitivity tolerance. It is advisable to skin test more regularly. In the event that you get a positive result this means you cannot go ahead with a colour service at this time. It does not mean that your client can never have a colour again. It is suggested that you wait a while, no less than 14 days, and then re test. You may find that you get a different result and can then go ahead with the colour service.
It is much better to be aware of what is happening. Knowledge is power and you have the power to be on top of your game and give your clients the professional service they deserve.
