Alot of salons have set times in which treatments should be finished in. You have to remember about cost! If you change £20-£25 for full leg and can do 2 in 1 hr then that's £40-50 an hour!! Compared to £7 you pay your therapist! And working for yourself your making £40 an hour! I do full leg in 30 min but block out 15 for underarm and 15 for eyebrows.take your time with eyebrows, they are the 1st thing people look at so don't rush and make then wonky or take chunks out. I do brush through ppls eyebrows with a disposable mascara brush, extra touch, but it gets the shape and makes them feel your actually good at what you do (as my book is in 15min slots) I do however use abc (Australian body care) wax which is in tubes like phd and disposable heads so it is sooooo much quicker because you don't gave to keep returning to your pot, it's also alot more hygienic and 90%of my new clients notice that! I think as new therapist it will take you longer, it's all about practice! But I have been to some SHOCKING places to try them out! It's as if the therapist is scared! It's going to hurt your pulling out hair .
