Small Cap Wig FAQs

What head circumference does an ALIGLOSSY Small Cap wig fit?

ALIGLOSSY Small Cap wigs are designed for head circumferences of 21–21.5 inches. Measure your head before ordering and check the cap-size details on the product page.

How do I measure my head for a Small Cap wig?

Use a flexible measuring tape around your head, following your hairline from the center of your forehead, above your ears and around your nape, then back to the starting point. Keep the tape comfortably snug, not tight. Measure with your hair arranged as you plan to wear it under the wig.

How do I choose between a Small Cap and an Average Cap?

ALIGLOSSY lists Small Cap for 21–21.5-inch head circumferences and Average Cap for 22–22.5 inches. A 21.5-inch measurement falls within the listed Small Cap range. If your measurement falls between these ranges or you are unsure which size to choose, contact us before ordering.

Why might an Average Cap wig feel loose on a smaller head?

If your head circumference is smaller than the cap size listed for a wig, it may feel loose or shift during wear. If your measurement is 21–21.5 inches, compare it with the Small Cap options in this collection. Adjustable straps may help fine-tune the fit when available, but check the listed cap size before ordering.

Can I wear a Small Cap wig over braids or thick natural hair?

Fit depends on your head measurement and the amount of hair underneath the wig. Measure with your hair arranged as you plan to wear it, then compare your measurement with the listed 21–21.5-inch range. If you are unsure, contact us with your measurement before ordering.

What textures are available in the Small Cap collection?

This collection includes human hair wigs in Body Wave, Water Wave, Deep Wave, Straight and Kinky Curly textures. Available styles vary by product.

What lace, density and length options are available?

The collection lists 13×4 HD lace front wigs in 200% and 250% density options. Hair lengths vary by product, so check the selected product page for its available lengths and exact specifications.

This was my first human hair wig as I was recommended this company by a friend. I will say this wig is not think at all. More like relaxed hair that is not very thick.

The lace is very thin and lays much easier than other units I have worn. The hair was full length was accurate hair quality amazing. Can't wait to install this !!!
