How can I remove the grease from this product?before using it...

I recommend washing your hair with gray soap. Before washing, I rub my hair in the places where the drug is applied with wet soap, after a few minutes I wash my hair with the system: 2x gray soap, 2x shampoo. After soap alone, the hair is "dull", but after shampoo it's ok. It is important how you apply the drug so that everything is not greasy. I first spray enough medicine on a plate (I designated one plastic only for that), apply Enstilar with a cotton swab pointwise / or apply it with a stick with my finger when the place is invisible and I have to do it by feeling. Then the fingers are not so greasy, so the hair along the length does not dream of mavelin, etc.
The oil didn't work for me at all (long, thick hair). When it comes to shampoo, I use the dermatologist's recommended "body and head wash gel, Pharmaceris Psoriasis". Maybe this information will help someone, good luck!

How do you apply rapeseed oil before washing? I'm a little afraid that I'll make my hair even greasy.

Hello. Enstilar helped me a lot, but when I wanted to wash my hair after this mousse, I first applied ordinary rapeseed oil to my hair, waited a few minutes and washed with shampoo 2x and there was no trace of greasy hair. I also had this problem and I searched the whole internet and came across this advice.
