we'll use the try commoners to do hair bundle measurements we'll look at the areas that are permanent for example in the back of the scalp and we'll measure that and see what is their maximum hair mass index that's the that's a term that we use for the number that is a combined measurement of the diameter and the density in a given area of scalp and then we'll compare that area to an area that might be at risk like the crown area or the frontal zone or in the temples and so it's normal to see a little bit less in the temple areas but when you're going through puberty your hair mass is essentially all the same over the entire top of your scalp so I can pick up if they have a tendency towards hair loss very very early on way before it's noticeable to the naked eye
