I have seborrheic dermatitis and I have been treating it with OTC shampoos for a few years to avoid the harsh prescriptions. I had been thinking about it for a while and finally decided to try this product as part of my natural care regimen for my curly hair and it works! I find that my scalp gets irritated and painful sometimes towards the end of my weekly wash cadence and this product helps relieve my scalp and keeps it healthier between washes. I am seeing fewer flakes than before and it relieves the irritation when I do get them. I find I don’t need to use it every day. I use it as needed, usually two to three times a week. I’d definitely say this is worth trying if you’re dealing with similar issues. For me it checks all the boxes- completely natural and safe ingredients, good for curly hair, formulated for seborrheic dermatitis (unlike other otc scalp products which are so vague in describing what they actually do for the scalp), it’s reasonably priced which is hard to find for this type of product, and it works! It’s also cool that it’s a small business and not tied to a large corporation.
