I only used it for a week, but my hair became much thinner and started falling out... My hair, which normally doesn't shed much, was coming out in clumps. The fallen hair seemed to have almost no roots, and I think my scalp got irritated because I developed seborrheic dermatitis (which can lead to hair loss if left untreated). I also got acne on my scalp, scabs formed, and it became red and inflamed. I really think it's best not to use this product if you can avoid it. I was prepared for some scalp irritation, but the risk of hair loss seems much higher than I expected. I used it in the second week of March and stopped in the third week, but I'm still seeing a dermatologist because the seborrheic dermatitis hasn't completely cleared up. I wanted to grow my hair a bit faster with this shampoo, but now I'm spending several times more money on prescription shampoo from the dermatologist. If you're considering using this product, please think very carefully about it.

My hair grows faster now. It grew about 1.5cm in just one week of use. The product definitely works.

When this shampoo is on a 1+1 deal, getting two bottles is a good choice. The conditioner and treatment are useless - they're so light that you'll wonder if they're nourishing your hair at all. Better to buy a different treatment. I ended up purchasing a separate hair cap, treatment, and scalp pack. This shampoo is so drying that you need that much nourishment. If you use a treatment, wear a hair cap for an hour before rinsing, your hair will be silky smooth!

It's fragrance-free, just unscented. I'd recommend using this for only 3-4 months when you're desperate with short hair. Is it because the cleansing power is too strong? It not only makes a dry scalp even drier but also causes flaking. I was shocked when I looked at the ingredients - now I know why. Still, I used it for half a year because I wanted my hair to grow fast. My scalp became a mess, but I couldn't stop because my hair was growing so quickly. Use it intensively, then quit cold turkey.

I've been using this for half a year now. I repurchased it with a 1+1 deal, and it's already been about six months. My hair has grown from a bob to past my collarbone - it's growing so fast! Even my regular hairstylist is impressed. Despite its liquid formula, it has great cleansing effectiveness.

I bought this hoping it would help my hair grow, but I don't see any difference... I have medium-length hair and it's really stressing me out. It's so disappointing. I wonder if other products will be just as ineffective...

I've been using this since December 24th. I've already finished the hair pack and conditioner, and it looks like I'll use up the shampoo today. The fragrance is quite pleasant.

If there's one downside, it's that there's no fragrance... (Though I'm not sure if that's just me!)

I cut my hair to a medium-length bob about a month ago, and then I bought this product. In just a month, it's grown almost to my shoulders! It's absolutely fantastic for speeding up hair growth.

I wash my hair once a day at night! Make sure to dry your hair completely before going to bed.

While the conditioner doesn't leak, the shampoo does if you lay the bottle down. Also, my hair texture has become quite stiff.

My hair tends to grow quickly, and with this shampoo, it grew 3 centimeters in just two weeks! Thanks to this, I find myself washing my hair every day now, whereas before I used to wash it every other day.

I admit it can make hair feel a bit dry, but that's easily solved with conditioner, so it's not really an issue.

My hair grows faster than expected! Many people have told me that my hair became more manageable after using this (without any treatments like straightening). I didn't experience any blemishes either.

There's a bit of a dry, straw-like feeling to it... Also, the amount is way too little.

Hair growth seemed faster than expected, and overall it wasn't too bad.

My hair is so damaged... I think a deep conditioning treatment is absolutely necessary.

It seems to grow more than twice as fast as usual! The scent is quite nice too.

It makes your hair a bit stiff, so shampoo alone isn't enough. A treatment or essence is essential. However, when you apply this, it doesn't feel extremely stiff, so it's okay.

I bought this because my short hair was in a terrible state, but it grew faster than expected. My hair usually grows quickly, but it was in such bad shape that it was hard to notice. Comparing photos, I can see it's definitely growing. It's working well even though I trim my hair often!

After getting a perm and using this shampoo, my perm completely fell out. I recommend not using it right after getting your hair done.

It seems like my hair is growing faster, but it might just be my imagination. My scalp feels refreshingly cool.

Wash twice daily, morning and evening. Massage scalp pressure points for 3 minutes, then rinse with lukewarm water followed by cool water. Apply the scalp hair pack, then do another pressure point massage starting from the forehead. Finish by applying treatment to the hair ends only. (★On weekends, apply the scalp hair pack, wear a cap for about 15 minutes, then rinse.★)

1. Drawbacks - While hair grows faster than usual, it becomes 'dry and lacks shine' = (Recommended to get a nourishing treatment at a hair salon). 2. Causes blemishes (scabs form) - Bought it because it's supposed to be good for the scalp, but my scalp is itchy and I have dandruff. 3. Not recommended for skin types - Combination dry + super sensitive skin (causes scalp blemishes + excessive oiliness = ★Never using this again).

Positive points - Hair grows twice as fast as usual, and the color doesn't fade even on dyed hair. That's great! (★Purchased the Secret Key Fast set: shampoo, scalp hair pack, and treatment trio★)

It seems to be more effective when I wash my hair every night rather than in the morning.

Since I have an oily scalp, it gets greasy quickly... And it doesn't grow super fast as I had hoped.

Hmm... I feel like my hair grows about 1-2cm more than when I use regular shampoo, and when used with a treatment, my hair texture has improved quite a bit.
