✂️ Maree's Studio Notes

This is your weekly intensive step in the Extreme Length system and it's a bit different to your usual hair mask — in the best way. Unlike most treatments which go on mid-lengths to ends only, this one is applied from the scalp all the way through to the ends. That's because healthy hair growth genuinely starts at the scalp, and this mask works on both — nourishing the scalp environment where your hair grows while simultaneously strengthening and protecting the lengths you're working so hard to keep. Once a week alongside your regular Extreme Length shampoo and conditioner routine is all it takes. If you're serious about growing healthy, strong hair this is the step that really pulls the whole system together.
