This oil is very useful for me. I have a dry scalp and in winters specially the scalp tends to turn super dry.
I am using it for 2+ year now. Good product for me. I am using it since I was studying in Alliance College in Bangalore about 3 years back. Its mainly available in Bangalore because when I was working in Chennai too, I could hardly find it in any shop. And forget about North India which was ZERO availability for the same.
North India has its own set of manufacturers who sadly have ill worked for me :p buy it at various sites online like kavya(kayya), clickoncare, etc
All of them have been good. Lately started using clickoncare: https://clickoncare.com/nisargalaya-root-hair-oil-100ml
I have no complaints against it except for its Smell which could have been better. I recommend alternate day usage in case you have dry scalp.
