I See Some Almost Invisible Hairs at My Hairline

Hi doc,i just have a question,I am almost 21 and I think I have a mature hairline,my hairline started to change when I was 19 years old.I have a widows peak and in the widows peak I noticed that there are like some vellus hairs that are almost invisible between the terminal hairs,the rest of my hair is thick and healthy but the thing that worries me is that they can be miniaturized hairs.You said that it is normal some miniaturization at the beginning of the hairline.

Yes, vellus hairs are normal. You will have them everywhere on your body. Some miniaturization is normal at the very front at the beginning of the hairline.
