I waited a few weeks to write this as I always read reviews about Brazilian blow dry written the day after and was never sure if they really work long term. Well, it’s been about 3 weeks now, best thing I’ve ever done, if I blow dry my hair it’s poker straight, super shiny and frizz free. If I let it dry naturally it’s pretty much straight and shiny with a bit of a kink. Before the treatment I had curly and frizzy hair, now if I experience a little drizzle or mist it doesn’t matter hair is still smooth. Best thing I’ve ever done, wish I did it years ago when I think of all the times I stressed about my frizz. The only downside is that I opted for the stronger version (recommended by the stylist for my hair type and the outcome I wanted) and leaving it on for 3 days it did leave me with a really itchy scalp and dandruff for about a week afterwards, there were a few small patches that looked a little like a chemical burn around my hairline and ear so I would recommend maybe using a baby wipe to wipe around the hairline before the treatment is blow-dryed in. Despite this I would 100% recommend and have it done again. Staff were so nice and did an excellent job.
