Everybody is Talking About: Glass Hair

Most procedures for achieving glass hair recommended use of a heat protection spray before styling, as well as applying hair serum conditioning products and a hold spray afterwards. While the efficacy of heat protection sprays is a contested area, the use of conditioning products prior to straightening and a hold spray straight afterwards are likely to be significant contributors to the ‘glassiness’ of the hair after treatment.
