Just before salons in England were allowed to reopen on 12th April 2021, BABTAC issued a statement that patch testing for relevant treatments should only be carried out 2 weeks after a vaccination. This did cause a lot of anxiety but there was a very good reason for this statement.<\/p>\n\n\n\n

There had already been a lot of advice suggesting that on reopening every client should be patch tested regardless of the last date. This was due to the fact that scientific evidence was showing the many people had a change in their immune systems if they had had Covid19. Many had been left with \u2018long Covid\u2019 and, as many have been un-symptomatic they may be unaware of having caught the virus.<\/p>\n\n\n\n

By patch testing every client for the relevant treatments (e.g. hair colour, lash and brow tinting, waxing etc) on returning it is safeguarding clients against the unexpected possibility of having become sensitive or allergic to the products.<\/p>\n\n\n\n

The NHS and Public Health England noted that some were getting side effects after having received the vaccination and that these should go after around 7 days. This suggested that the immune system was working hard, the client may feel unwell and a patch test result may not be accurate. Again, in the interests of safeguarding the client, the suggestion was to go a bit beyond the 7-day suggestion to 10-14 days.<\/p>\n\n\n\n

There were many comments that we should be following the \u2018science\u2019 rather than \u2018opinion\u2019. There is evidence that the immune system can be compromised following C19 either permanently or temporarily. BUT there is, as yet no \u2018science\u2019 around patch testing as salons have just opened so there has not been enough time to collate any results. Therefore the whole issue of \u2018mitigating risks\u2019 came into play. BABTAC were suggesting \u2018best practice\u2019 and a demonstration of \u2018duty of care\u2019 and \u2018due diligence\u2019.<\/p>\n\n\n\n
