Review (3/5): Pretty Good
I got the T1B/30 and the 1B. As many have mentioned, the T1B/30 is much lighter than expected and isn't really Ombre. I'd say there's hardly any 1B in it. It's a light brown with lighter brown tips lol. Buuuttt I got the 1B in anticipation of that to mix with the T1B/30. Combined it makes the look I was going for, but separately I would have returned the T1B/30 as it doesn't match the picture.
There was no smell with the hair, but it did irritate my skin when I did a test twist. I'd say to probably wash/condition/soak the hair before install to avoid the itching or rashes.
