I purchased GSO and it was still too heavy on my hair. I use it on my body now. I've settled on the few oils in my conditioner to be sealy enough for me. Anything extra just my makes my hair greasy and limp and resistant to conditioner.
Of course I have finer hair, so maybe you'll have different results. The great think about oils are that they are super cheap, so it won't hurt to much to try.
