"Hair, just like a plant. You may nourish the leaf, but it doesn' t mean the root is healthy." While j.f. lazartigue products exist to address every types of hair problem (e.g. hair loss, dry/oily hair, dandruff etc) and restore hair to its healthiest look and feel, products are most effective when the right ones are used, and used properly. Proper analysis and diagnosis can be done under a Numberic Hair Analyzer which enlarge the hair image in 180 times in order to examine the health condition of hair shaft, scalp, and most importantly the root.
