Early verdict · Few reviews so farWhat the gurus are saying
This serum earns praise for its lightweight, refreshing texture with a cooling, minty sensation that feels good on the scalp and can be worn daily. The rosemary oil and other topical agents are considered potentially beneficial for hair growth, though results take time beyond a month. The main trade-off is the premium price point, and it's best suited for those committed to consistent scalp care over weeks.
