I have only been using the shampoo, conditioner and serum for around 2 months and have seen some improvement in the hair density. My parting seems fuller.
I only wash my hair 2-3 times per week. It does seem a bit dryer so have been putting conditioner on the ends prior to washing which seems to help.
Hopefully the improvement will continue and I will have more thicker hair with more growth around my hairline by the 6 months mark
