My last set of highlights ended up making my hair too blonde, stylist did not listen at all to my request and I won't be returning to that salon again. Unfortunately my finances have recently taken a nosedive and I can no longer keep up with regular appointments to top up my highlights. Any recommendations of what I can do to my roots to blend darker hair through to reduce the need for further visits? Kind of ombre/balayage look which won't cost a fortune!
