Yeast Hair Treatment
Brewer's yeast, 맥주효모, is one of the ingredients Korean scalp care leans on hardest, and this collection holds the treatment side of it: rinse-out conditioners, hair packs and the treatment halves of shampoo bundles. Read Beer Yeast and Brewer's Yeast as one ingredient. They are two English renderings of the same Korean word, which is why KUNDAL's Citrus Pomelo tube appears under both spellings. Most of these carry hair loss relief wording, which in Korea is the MFDS functional designation 탈모 완화 rather than a promise of regrowth. Sizes run from 200ml tubes and 200g packs up to 1000ml salon jugs, and several records are two-piece or three-piece sets where the treatment ships with its matching shampoo.

Choosing a brewer's yeast hair treatment
Brewer's yeast entered Korean hair care through the scalp aisle, and the treatments here are built around two ideas: protein for the shaft and B vitamins for the scalp. What separates the products in this grid is less the yeast itself than the format, the size and whether the treatment comes on its own or bundled with a shampoo. This guide walks through those choices and through the wording on the labels, which is more regulated than it looks.
What brewer's yeast contributes
Brewer's yeast is a by-product of beer fermentation, dried and milled. It carries a high share of protein along with B-group vitamins including biotin, plus zinc and selenium. In a rinse-out treatment the protein fraction is the part that does visible work, filling gaps in a damaged cuticle so hair combs more smoothly, while the vitamin content is the part the marketing leans on for the scalp. Bierhefe names this directly with its Hair Protein line at 500ml.
Beer yeast and brewer's yeast are the same thing
Korean labels say 맥주효모, and English listings render it either way. KUNDAL's 200ml treatment appears in this collection as Beer Yeast Hair Loss Treatment Citrus Pomelo and as Brewer's Yeast Hair Loss Treatment Citrus Pomelo, one product with two translations. The same happens to Crazy Skin's 200g Treatment Hair Pack and to AVCA's 1000ml Scalp Care. Bierhefe is a third variant, the German word for the ingredient used as a brand name.
What the hair loss wording means
Products sold in Korea as 탈모 완화 hold an MFDS functional cosmetic designation for hair loss relief. That covers reducing shedding and supporting scalp condition. It is not a licence to claim regrowth, and none of these treatments is a medicine. If you are shedding heavily or seeing a receding pattern, a treatment like AVCA Scalp Care Hair Loss Relief 1000ml is a reasonable part of a routine, not a substitute for seeing a doctor.
Tube, pack or jug
The 200ml tubes from KUNDAL are everyday conditioners you use after each wash. Crazy Skin's 200g Treatment Hair Pack is a heavier mask for once or twice a week and needs a longer sit before rinsing. The 1000ml bottles from AVCA and Derma fume are salon fills, cheapest per use and sensible if the household is sharing. Grainic sits between the two at 770ml. Match the format to how often you will actually use it rather than to the headline price.
The bundled sets, and when they make sense
Six of the eighteen records are bundles rather than single treatments. Dr. Scheller sells Beer Yeast Hair Protein Nutrition as a two-piece and a three-piece shampoo plus treatment set, Bierhefe offers a two-piece and a pack of two 500ml shampoos with one treatment, and Soleo's Dr. Bangiwon three-piece adds a 150ml hair tonic to a 1000ml shampoo and treatment. Buying the pair is worthwhile if you want the shampoo and treatment from the same line, since the scent and the surfactant base are matched. If you already have a shampoo you like, buy the treatment on its own.
Scent is a real choice on this shelf
Yeast has a distinct smell and brands cover it. KUNDAL sells the same 200ml treatment in Herb Mint and Citrus Pomelo, with the mint version giving a cooling feel on the scalp that suits oilier hair, and Rubskin's 500ml comes in a Blooming Floral. The heavier salon fills tend to be more neutral. If you have found yeast products unpleasant to use before, the scent was probably the reason rather than the formula.
Applying a yeast treatment properly
After shampooing, squeeze the water out of your hair first. Treatment applied to soaking hair dilutes and slides off. Work it from mid-length to ends, and keep the bulk of it off the scalp unless the label says it is a scalp treatment, since a rich conditioner on the roots is a common cause of hair looking flat and greasy within a day. Two to three minutes is enough for a daily conditioner; a 200g hair pack wants five to ten. Rinse until the hair squeaks slightly between your fingers.
Pairing with a yeast shampoo or another active
Yeast shampoos are a much larger category on this site than yeast treatments, so most people arrive here having already picked the wash. Staying inside one line keeps the scent consistent, but there is no formulation reason you cannot pair Derma fume Wine and Brewer's Yeast 2X with a different shampoo. If you are also using caffeine or rosemary scalp products, those work on the scalp while the yeast treatment works mainly on the shaft, so they stack without competing.
FAQ
Frequently asked questions
FAQ
Frequently asked questions
Why does the same KUNDAL treatment appear as both Beer Yeast and Brewer's Yeast?
They are two English translations of 맥주효모, the Korean name for the ingredient. KUNDAL's 200ml Citrus Pomelo and Herb Mint treatments are each listed under both spellings, and Crazy Skin's 200g Treatment Hair Pack and AVCA's 1000ml Scalp Care do the same. Compare the size and the price rather than assuming the two records are different formulas.
Will a brewer's yeast treatment regrow hair?
No, and the Korean labels do not claim it. The wording on products such as AVCA Scalp Care Hair Loss Relief Treatment is the MFDS functional designation for hair loss relief, which covers reducing shedding and supporting the scalp. Expect less hair in the drain and better condition along the shaft. Regrowth is a medical question.
Should I take a 200ml treatment or the 200g hair pack?
The KUNDAL 200ml tubes are everyday conditioners for use after each wash. Crazy Skin's Beer Yeast Treatment Hair Pack 200g is thicker and meant to sit for five to ten minutes once or twice a week. If your hair is damaged, use both: the pack on wash day and the tube in between. If it is only slightly dry, the tube alone is enough.
Are the shampoo plus treatment sets better value than buying the treatment alone?
They are if you want the matching wash. Dr. Scheller's Beer Yeast Hair Protein Nutrition comes as a two-piece and a three-piece, Bierhefe sells a two-piece and a two-shampoo-one-treatment pack, and Soleo's Dr. Bangiwon three-piece adds a hair tonic. The per-item price is lower in a set, but you are committing to that line's scent and cleansing base across the whole routine.
Do I put a yeast treatment on the scalp or only on the lengths?
Lengths and ends, unless the product says scalp. AVCA and Soleo build their 1000ml bottles around scalp care and say so in the name; KUNDAL's 200ml tubes are conditioners for the hair itself. Putting a rich conditioner on the roots is the usual reason hair looks greasy a day after washing.
Which scent should I pick between the KUNDAL and Rubskin treatments?
KUNDAL's 200ml tube comes in Herb Mint and Citrus Pomelo, and the mint version leaves a cooling feel that suits an oilier scalp. Rubskin's Premium 500ml is a blooming floral, heavier and sweeter. The 1000ml salon fills from AVCA and Derma fume are the most neutral of the group. Since a rinse-out treatment sits on the hair for only a few minutes, the scent you notice afterwards is faint, but it is the difference people report most.
Is a 1000ml bottle too much for one person?
It can be. A litre of rinse-out treatment used by one person on shoulder-length hair lasts well over a year, which is longer than the period-after-opening on most of these. AVCA, Derma fume and Soleo make sense for a shared bathroom or for long, thick hair. Otherwise the 200ml, 200g and 500ml options finish inside their shelf life.
