Hair testing for all hair types
ALS offers the full range of sensory and instrumental claims studies on human subjects. We can recruit for any race/ethnicity of subject or for specific hair types such as blonde, brunette, curly, kinky, oily, dry, etc. Studies can be conducted either in a salon setting or as take home. Typical claims include shine, softness, growth, density, comb-ability, smell, or general health.
