BLOO is a unique scalp treatment formulated to alleviate dandruff, soothe itching and irritation, and replace toxic shampoos. The formulation is remarkably simple:
- 1.5g salicylic acid
- 3g baking soda
- 1g vitamin B3
- 1g taurine
- 500mg caffeine
- 20mcg methylene blue
Simply mix one tablespoon in 4oz warm water, apply and massage into your scalp in the shower, and rinse after 5-10 minutes!
Note: We have recently reduced the amount of methylene blue in our formula to avoid staining bathtubs and showers. If you have recently ordered and are dissatisfied, please email hi@trybloo.com and we will give you a full refund. However, please give the new formulation a try first, it should be just as effective as the prior formulation.

I see way less shedding and I don't have an itchy scalp anymore.
Having always had a fairly sensitive scalp, I often struggled with dandruff and itchiness when using most commercial shampoos even while using conditioner.
A week into using BLOO and I've done away with both the dandruff and the conditioner
First use, itchiness and swelling was calmed considerably
Second time, my scalp became very happy
Third use, itchiness, swelling and flakes are gone
My hair is growing along the hairline, feels and looks fantastic
I’m never buying shampoo again, ever
Bloo is amazing!
After struggling with a mysterious head sore problem that suddenly appeared, I have used Bloo consistently and it is now resolved!
I use it regularly a couple times a week or so, and especially at the first sign of any bumps or itching, before they can progress into sores. Now my scalp is getting back to normal. I will continue using this to see if I notice any new growth coming in, as this was a secondary goal to getting my scalp clear again.
Thanks guys, this product is great!!
Everyone at Blooo is so amazing patient and helpful overall, The products speak for themselves and the team and company is top notch!
