Annie's Hair Club in Chula Vista occupies Suite 202 at 20 Third Avenue—inside the CVS plaza at the corner of Fourth and C Street—serving men, women, and children with a full hair-care menu plus waxing and hand paraffin treatments. The service list pairs haircuts with color, highlights, perms, texture treatments, and chemical straightening, a breadth of options that parallels the specialty nail work at NAILCESSITY Nail Salon. Retail shelving stocks Joico, Paul Mitchell, Chi, Johnny B., and Kenra product lines, giving clients take-home maintenance matched to their in-chair chemical service. Perm and texture services use alkaline and acid thioglycolate formulas selected by hair diameter and porosity, a chemistry-first approach to wave pattern and curl formation. That product-and-service pairing—salon-formula color followed by a brand-matched conditioner—reflects the same retail-salon integration found at European Wax Center's post-treatment skincare program. Chemical straightening treatments apply keratin-bonding or formaldehyde-free smoothing solutions under flat-iron heat to break and reform disulfide bonds, reducing curl and frizz for up to three months per application cycle.
