In case it is of interest to anyone:
Most likely not.
Probably best to keep the older Hair Growth and Recovery (or possibly Hair Loss Treatment Ver 3.0) in the stack to further counteract hair follicle miniaturisation effects, remove DHT buildup and confer resistance to DHT in the follicles.
From the Hair Growth and Recovery helps with Hair Loss (updated ver2.0) description:
It will place follicles on your scalp in the anagen phase, it also uses HGH, Lin28a and stem cells targeted to the follicles to strengthen, thicken and recover them.
It also will try to remove any DHT buildup in the scalp.
While making them resistant to DHT as well.
Updated.
added to this is lactate to activate the dormant hair stem cells.
and 5-Azacytidine to the skin cells (to create even more stem cells)
From the Hair Loss Treatment Ver 3.0 description:
It will induce the follicles on your scalp to go into the anagen phase, it also uses HGH, Lin28a and stem cells targeted to the follicles to strengthen, thicken and recover the follicles.
DHT buildup will be removed and reduced.
Stem cell production will also be induced.
Added to this version, blood vessels are dilated to increase blood flow, far light infrared is also targeted to the scalp and finally, Janus kinase (JAK 1, 2, 3 and TYK2 ) are inhibited.
