Hello.... welcome along ... What type of thinning / recession are you seeing ? [Front hairline and / or temples ] ....at your age, it`s particularly stressful to see hairloss setting in...... I`d advise you not to just rush into wearing if you are only just beginning to thin......once you make the leap, you need to be able to ` deal` with wearing, psychologically......it can have it``s limitations and ` issues` , but I reckon it`s better than the alternative ! if you`d like to post a few photos [doesn`t need to show your identity ] you`ll most likely get more responses , as people can see your situation.
Yes it`s possible to trim-out an area from a lace stock system.....stocks are all medium density, and come in a few different colours.... there`s no guarantee that a particular one, would be a good match for your individual hair-colour..... but it`s possible also , that it could be perfect ! --just ` depends` ...... regards .
