I wanted to like it.
Got 2 bags, they weren't powder at all, just a brick of product I had to break up into chunks. It didn't foam. I think my was faulty.
Zero response from customer service.
I thought I hated soap … then Bloo Bar walked into my shower like a tiny superhero and changed my opinion forever.
I have had dandruff on the back of my scalp for about a year. Tried many many products to no avail. BLU actually is healing whatever is going on back there.
It’s a great product! You should buy this!
I notice the strengthening effect and my hair colour seems to be more noticeable too, as in not so dull. Definitely a helpful product, and seems to increase hair growth to a degree too.
