First of all, I wasn't prepared for the messiness of it. If you have short hair, I think it wouldn't be so bad, but the long hair? What a mess!! Pete says I'll get better at it each time -- I hope so.
I ended up buying Light Mountain Natural Henna Chestnut which appears to be pretty cheap at $4.95, but you have to pay that again in shipping. I *so* wanted to try the Lush henna, but it's been out of stock for a long time.
Wish me luck washing this stuff off. I am very afraid!
