Tape-In Extensions

Tape In extensions are the newest hair extension method on the market.Tape in extensions are thin tape wefts, generally 1.5 inch wide pre-taped hair wefts, that get “taped-in” in between your own hair in “sandwich” like bonds. It is the most requested professional hair extension method in salons worldwide. This method is 100% natural, requires no tools or chemicals, and lasts up to three months-and the hair is reusable! It takes less than an hour to apply an entire head with zero damage.

Sew-In Extensions

This method uses soft silicon beads and nylon string to sew in wefts using a curve needle. The result is fuller or longer hair. Placement is custom to every head shape and desired look. The beads travel around the head allowing for consistent tension, so hair is never overdirected or pulled causing breakage or damage.

I’ve been going to 4&Co Salon for almost 2 years now and am obsessed! Everyone here is a gem and they will take amazing care of your hair. Not just with color and cuts, but also deeply invested in the health of your hair. Can’t ask for anything more!
