What do md hair reviews actually tell you about regrowth?

How MD Hair actually targets thinning follicles

The mechanism is buried under the glow of the marketing copy, so let's dig it out. Most of what's in this formula, the collagen, the general vitamins, is the same base every hair supplement on the shelf leans on, there to give strands raw material to build with, not to change what's happening at the follicle. The part actually doing targeted work is the saw palmetto, and its job is narrow: it interferes with the enzyme that converts testosterone into DHT, the hormone most linked to shrinking follicles in pattern hair loss. Less DHT reaching the scalp means follicles that were miniaturizing get a longer runway to stay in their growth phase, a slow, cumulative effect rather than a switch that flips. L-lysine is doing a quieter second job, helping the body absorb and use iron, and low iron is one of the more common, more fixable reasons hair thins that has nothing to do with hormones at all. That combination is also why the claim about supporting PRP and restoration treatments is more honest than it first sounds. It isn't claiming to grow hair on its own, it's claiming to reduce the shedding that undoes what a procedure like PRP is trying to hold onto. That's a real, modest job, and a completely different one from reversing hair loss caused by thyroid problems or stress, which saw palmetto's pathway doesn't touch.
