You need to pick your hairpiece after determining the pattern of thinning of your hair. This will allow you to decide whether you need a hairpiece that covers your entire head, or you only have a few thin patches which can be easily camouflaged using hair extensions. Depending upon your study, you may want to choose any of the following hairpieces.
Similar to wigs, falls also cover the entire head. However, unlike wigs, they do not fit tightly on the head, but have clamps for attachment. These clamps or combs are to be attached on the front hairline to secure a fall in place.
The other type of fall is used to cover the thinning patches in some areas of head. Thus, falls are useful for women with thinning only on some parts of the head.
If you have enough hair on the head, but have marginal hair at the back, then this hairpiece could be your option. Ponytails come in different lengths and volumes, so you can choose one which resembles your natural hair growth. You can also easily match the color with your natural hair, since they come in almost all natural hair colors.
Weaves are a semi-permanent solution for hair loss. Unlike the three hairpieces mentioned above, weaves are directly sewn into the head. Natural hair is braided in rows, so that weaves can be sewn in between them. This can last for about 4 to 6 months.
Hairpieces are indeed a great way of retaining your good looks, since they alleviate the damage due to hair loss. However, it cannot be seen as a permanent hair loss solution. To grow your original hair back, you have to undergo clinical treatment only, since that is the true solution for thinning hair.
