Pros
I've tried taking brewer's yeast in powder form before, but this is the first time I've used it as a shampoo. My hair has been gradually thinning, so I looked into it and found that brewer's yeast is good for hair loss. I came across the Merchen brewer's yeast shampoo, and the ingredients and price-to-volume ratio seemed decent, so I decided to buy it. I received it today and tried it out this evening. The lather was good, better than some reviews I had read. I was worried the yeast smell would be strong, but it had a mild, slightly sweet scent, and it didn't make my hair too stiff. I'm hoping the hair loss relief function will be effective for me.
Cons
20 key ingredients and 1 fragrance, with 1 allergenic component, so it's a bit disappointing... but it's still relatively good.
Tip
After rinsing with the pre-shampoo, shampooing thoroughly one more time results in rich lather and a refreshed feeling.

Pros
It feels refreshing and cooling on the scalp as soon as you use it! Even though it's a functional shampoo, your hair doesn't become stiff but remains soft, and the lather is rich and abundant. I've been using it for a few months, and the itchiness and sensitivity of my scalp have definitely decreased.
Cons
When I rinse with water, there's a slight film-like feeling, and it feels like an oily film, so even though I just used this shampoo, I can feel the oiliness returning to my scalp. This happened even in the winter, and I think it will be even worse when I use it in the summer..
Tip
Using this shampoo alone for a whole week is not necessary. Using a different shampoo in between can help reduce the oily issue and be beneficial.

Pros
The product contains 10,000ppm of brewer's yeast and various ingredients that are good for hair loss, and apart from the fragrance, all the ingredients are relatively mild, so I decided to purchase it. :) When I used it, even though the formula is on the thinner side, the lather seemed to form well. The value for money is also amazing, and they even had a good promotion, which I was happy about. Oh, and I noticed a refreshing and cooling sensation when using it, and it turns out there is a menthol ingredient! I think male users would also like it, and it would be great for summer use. ㅎㅎ The cooling sensation is not so strong that it can't be used in winter, so I think it can be used well even in the winter :)
Cons
The fragrance was not quite my type 🥲 The fragrance is actually important in a shampoo... The description mentioned rose and caramel scents, and that's exactly what I got. ㅋㅋ When I read the description, I didn't know what it meant, but when I used it, I immediately understood. It's really sweet~~ But there's a certain heaviness to the sweetness? ㅠ It doesn't seem like a high-end fragrance. It was similar to the scent of some cheap amenities. ㅜ This is the most disappointing part, and there's nothing else.
Tip
It's said that the best habit for preventing hair loss is to wash your hair in the evening. :) Try washing your hair with this shampoo in the evening, and after washing, I recommend using a conditioner as well, as some people may experience a slightly dry feeling.

Pros
This is a scalp suitable for the Arctic region. I bought it on sale at a cheap price, and I'm hoarding it because I like it so much. First of all, it's good that it doesn't contain sulfate ingredients. It contains menthol, so the roots feel refreshing and cool. And the lather is abundant, and it's not too stiff even without using conditioner. And for sure, my hair falls out less when I use this. The fragrance is very subtle, so there's hardly any scent left after washing.
Cons
As for the downside, hmm, there's nothing, nothing, nothing, nothing.
