Are there different sizes of the Capillus cap available?Updated a year ago

• Regular caps fit most heads, up to 24" in circumference (comparable to a size 7 hat).
• Extra-large caps, comparable to a size 8 hat, are available upon request by contacting Capillus customer service at 1-888-272-9599.

For smaller hat sizes, as long as the cap is within 2 cm all around (3/4”), it is effective. Therefore, anyone with a head measuring 21” or larger will be fine with a standard Capillus cap.
