CH6 Green Beer Lab Aloforthya Serum is a leave-on scalp serum with an unusual base: the ingredient list starts with 54.92704% green tea extract and 15.09200% Saccharomyces cerevisiae extract. That makes it much more botanical and ferment-forward than a typical water-first scalp tonic.
What is a scalp serum for?
A scalp serum is optional. Its job is to add a leave-on care step after cleansing, usually with a lighter texture than a hair mask or conditioner. It should not be confused with a medical hair-growth treatment.
Why is the green tea percentage interesting?
Green tea extract is the first ingredient and is listed at more than half of the formula. That is unusual enough to be meaningful rather than decorative label copy. The formula also includes brewer's yeast extract as another major component.
What else is in the formula?
Niacinamide, panthenol, salicylic acid, biotin, ceramide NG, caffeine and zinc gluconate appear alongside a long botanical blend. Menthol gives the formula a cooling feel. The product also contains alcohol denat. high on the ingredient list, which helps create a fast-drying texture but may not suit a very dry or reactive scalp.
Who may like it?
It makes the most sense for someone who enjoys a fresh scalp-care step and wants a light leave-on product rather than an oil. It may be less appealing if your scalp reacts easily to alcohol, menthol or fragrance.
How to use it
Apply a small amount directly to the scalp in sections and massage gently with fingertips. There is no benefit to soaking the scalp. Start conservatively so you can judge how the formula feels over several uses.
Can it reduce hair loss?
CH6 uses stronger functional language in its Korean market, but an imported cosmetic scalp serum should not be treated as a substitute for evidence-based assessment or treatment of persistent hair loss. For a retail skincare/haircare routine, the realistic role is scalp conditioning and a refreshed feel.
Bottom line
The most distinctive part of this serum is the genuinely high green-tea and yeast-extract content. Whether that is worth adding depends less on the ingredient count and more on whether you actually enjoy a leave-on scalp step.
