Didn’t quite do its job

I had bought this scalp oil along with the scalp scrub because I was experiencing some dry and flaky scalp. I saw reviews on Google that the oil and the scrub together just helped moisturize and exfoliate at the same time. After using the scalp boil I’ve figured out that it doesn’t actually absorbing into your scalp very well. It more just sits on the top and makes your surrounding hair greasy no matter how much you rub it in. I’ve used under the amount the bottle says and over the amount and I keep having the same experience. My scalp is less itchy the morning after I use it, but I feel it just doesn’t fully complete its job. After I am done with this line of scalp care I will probably be finding a new one. At the same time though it’s not so horrible that I’m just gonna stop using it. I just feel like there are better products out there that are going to help moisturize my scalp and actually soak in.
