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.

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.
I've been using Bloo for my hair for 6+ months now and it has been a fantastic addition to my hair care - I've seen great improvement in my hair health and scalp health with far less itching and dandruff. I tried the soap when it launched and have been using it ever since - it's the only soap I've tried that restores the natural oil in my face rather than leaving me dry like Dove or other big brand soaps do.
The only thing that treats my seborrheic dermatitis and leaves my hair light and clean.
Heard about bloo from a random comment on a Twitter post. Really like the results, strengthens hair and deep cleans the scalp. I’ll be a repeat buyer
