BEARD oil is only ment to imrove the quality of beard not the hair growth. Hair growth is totally based on Hair follicals present on your face and hair receptors . Any sort of beard oil wont help . Beard oil will only lubricate your hair just like oil in your scalp. I liked this product because it makes my beard more fluffy and soft , nothing else.
Advantages: -
1) Makes hairs soft ( If you have)
2) makes beard smell good
3) kills bacteria
4) Avoid itchiness
5) Quality product
6) Shines the beard
7) Used for styling of beard
Disadvantages: -
1) Costly
2) Doesnt Grow new hair
3) Its a bit concentrated
4) May have allergic effect
Overall: -
I dont recommend if you are trying to grow more hair but I do recommend if you have full thick beard.
