Hair Regrowth vs Thickening

hello, I’m a little confused about what hair regrowth is and what hair thickening is. is regrowth when hair grows where it isn’t or is it when a small hair thickens?

Regrowth is when hair grows where it once was. It’s all a matter of semantics. One can thicken the appearance of a head of hair by increasing the number of hairs in the head (regrowing new hair), moving the hair around (transplant), using camouflage (pigments), or increasing the thickness of existing hair (products). This is done by:

1. Reducing the degree of miniaturization with drugs like Propecia (finasteride) so that each miniaturized hair will become less fine and more coarse (closer to your normal hair in the donor area).
2. Increasing the thickness of the individual hair shafts with thickening agents that are applied to the hair which cause them to take on more water, or coat the hairs with some product that makes them appear thicker (this is done by applying a product to the hair that will usually wash off when shampooed).
3. Increasing the thickness of an area can be done through hair transplantation. This is a relatively permanent solution until you lose more hair (it’s progressive).
4. By playing with color, someone can bring their hair color closer to their scalp color with chemical dyes or the use of scalp micropigmentation (a medical tattoo). The use of agents such as Toppik (adds fibers to the hair and scalp) or DermMatch (a crayon type application to bring color to the scalp.

So you see, there are many ways to get a fuller look that may not be the results of a full head of hair, but if it fools the eye, then many people will be satisfied using these approaches.
