Whats the difference between HD lace and Regular lace ?

Brow lace can only math to brown skin or dark skin ,the lace is hard , and not invisible , the hair knots looks obviously ,but the HD lace is real invisible ,and it can match to all color skins , the hair knots looks more natural , and the lace is super soft, comfortable to wear .

Regular transparent lace is invisible , but not real invisible like HD lace ,and not as soft as HD

 lace .HD lace is made with thinner string so when you wear , it can almost fade in your skin .

But does HD lace has its defect ?  

The only defect of HD lace is that , its not as strong as the regular lace , because the lace string is very thin .so when you apply the HD lace , you should be more careful .
