Review (5/5): Works best if your already blonde!
I loved this product...it last 3-4 weeks in my hair and I get tons of compliments on it. I work it into my hair like a shampoo/condition and let it set for 20-30 minuets then rinse. It has done no damage to my hair and I will continue to buy for touch ups. I do however recommend that if you have long or thick hair your buy more than one pack, my hair is medium length and thin so one pouch works for me.
