Toplace densities are heavier than some other suppliers .... there`s no real ` standard` figure/benchmark ..it varies from one supplier to another and also, some of the individual ventilators seem to get a bit over-enthusiastic I reckon.
TL ballpark densities are: Light-50/5% Medium-60/5% Medium to Heavy 70/5%
and Heavy- 80/90%. As a comparison, a TL density of 65% can equal 85% from other suppliers. The colour always looks a bit darker at first....it will ` lift` after a few shampooing`s and sun-exposure...... I always give my new systems 2 light shampooing`s...you`d be surprised how much ` excess` colour comes out....last system, the water went a really dark shade !
If you took your hair sample from the back/crown area, that hair is always darker than at the front/sides so it`s worth bearing that in mind....take bits of hair from a few areas.
Proceed cautiously with the thinning ...I used a cotton bud [Q-tip]...don`t put huge dabs of it on in one area [obviously] and also be aware, that not all the hair will shed out in one day..some hairs are weakened by it but don`t always shed out immediately.....you`ll see more hair shedding out over the next day or two when you brush the system.
I thinned mine over about a week with repeated applications.
Be good to see your pics when you post them..cheers.
