Well, I've had this serum for a couple of months now & of course, the 1st week I used it religiously. I tend to be kind of fickle, so I guess that since I'm not desperate for quick hair growth, it wasn't a biggie to me. I mean come on, oil every day or every other day. That's too much committment for me, so needless to say, I slacked off & even forgot about it.
Also, I generally used too much of it (bcuz I'm too lazy to take my time & apply it correctly), so if I used it right before bed, then I'd have a greasy pillow case, so I'd have to remember to use it a little earlier in the evening to prevent that.
Anyway, I give this 5 stars not for the growth it claims to give, but just for being a good oil that absorbs very well. I like the light smell too. And it doesn't leave a lot of buildup. I bet it does encourage hair growth if you use it as recommended since you tend to massage the scalp after you oil anyway therefore promoting growth.
This will be a repurchase for me.
