Should I wait?

I have my 2nd brazilian treatment due in a week, but I am only just seeing the 1st signs of regrowth after my last treatment 7 weeks ago. Is enough hair likely to grow within a week or should I rebook for say… 2 weeks time? (It can be hard to get appointments when convenient) How long will the new hairs stay in anagen?
Thanks

I had my second treatment after about 10 weeks and the third after 13 weeks. You can book for 3 or even 4 weeks from now. The hairs will still be in anagen. Personally I’d wait til it looks like everything that is going to come through, has. Then I’d book. But since convenient appointments are hard to come by, you have little choice.
