I'm 33 and my hair around my crown started thinning about 4 years ago but it seems to be very slowly thinning (thankfully!). At the moment it's still very thick at the front but it does cause me distress & anxiety so my hairdresser suggested using Super Million Hair which consists of fine particles of artificial hair which are sprinkled on your natural thinning hair. It really does cover well and looks so natural. Makes me feel so much better when I go out and also washes out easily.
