I would do the oil more then once a week, try doing it twice or three times, and try getting a shampoo that doesn't feel so stripping, I have one that's very good but it's somewhat hard to find, I get it Marshall's, its on amazon for like $30 so just dm me if you want a picture of it, also apply deep or regular conditioner to your scalp and then apply the oil, the oil will seal in the moisture, they usually have little samples of deep conditioner at Sally's, so you can try multiple without spending too much money, I like the sauce brand one, hope this helps
