No no no.
A wig is made with synthetic hair on a thick rubbery base of which a high hair density is used to cover up. Giveaway is the hairline, density, mismatched fake hair, shifting and the required wiggy hairstyle.
A hair system (at least a good one) is basically real human hair bonded to your head through a fine translucent lace that weighs less than a piece of tissue. Bond is strong enough that if my hair got caught in a drill press then my head would get scalped. Density can be as light as you want is the lace disappears with the grain of the skin on your scalp.
But no it's not a hair transplant and more of a very very very good wig-like solution. They just describe it as 'strand by strand' to reduce the shock of getting your head shaved for the first time as they bond the system on.
