Early verdict · Few reviews so farWhat the gurus are saying
Customizable formulas that you tailor to your hair type and needs earn praise for manageable, shiny, bouncy hair and convenient delivery. The fragrance-free option is valued by those with fragrance sensitivities. Some reviewers have used them for years and keep repurchasing, suggesting real-world staying power. Hair loss concerns, however, aren't the focus; results don't extend there.
