Adenosine
Thicker hair shafts and a longer growing phase, in men and women who are already thinning.
Also called Topical Adenosine, Adenine Riboside, 9-β-D-Ribofuranosyladenine
Who it's forAny man already on minoxidil who wants more without a prescription.
The item
Three squares: proven in human trials. Two: a strong signal. One: early human data. Striped: the trials disagree.
Why it works
At the base of the follicle it activates adenosine receptors on the dermal papilla cells. Those cells respond by releasing growth signals, including factors that stimulate follicle cells and improve local blood supply. The net effect is a longer growth phase. Minoxidil targets the same result by a different route.
Where it fits
Adenosine is a move in one protocol. Each one opens the plan it sits in.
What people say
Here is what doctors, influencers and men online say about Adenosine, word for word.
Experts
Clinicians, authorities
“However, the patients were significantly more satisfied with adenosine because of faster prevention of hair loss and appearance of the newly grown hairs.”
“as part of a regimen and 17 are not recommended (adenosine; cetirizine; carboxytherapy; amla syrup; microfilament thread”
“The results from clinical trials published until now suggest that topical adenosine increases hair thickness, reduces excessive hair loss, stimulates hair regrowth, and increases hair density.”

“Topical adenosine applied for 6 months increased the proportion of thick hair in two placebo-controlled trials of 140 men with male-pattern baldness”
“My guess is that the before and after results did not prove comparable to those from Minoxidil.”
“Clinical studies suggest that while adenosine is unlikely to treat hair loss or increase hair counts meaningfully, it may modestly improve hair thickness or fiber diameter over longer periods (around 12 months).”

Forums, reviews, comments
“the Adenosine product has been good for me in slowing hair loss”
“But in the paper it shows a synergistic formula which was more effective across the board than the two by themselves.”
“due to a faster cessation of hairloss, but its long-term usage was not superior to minoxidil. Meaning, same results, but faster.”

Add adenosine to your minoxidil. It thickens the hairs you've still got.
