Hey babe! So you know how I’ve been testing like a million hair products lately? I finally found something that made my friend literally stop me on the street to ask what I’m using 😅
The Dr.FORHAIR Folligen Thickening Shampoo has been selling out at Olive Young for a reason, and spoiler alert: it’s not just hype. Let me break down everything I learned!
Dr.FORHAIR Folligen Thickening Shampoo 750ml Set (+100ml*2ea)
✨ Best for: Thinning hair, flat roots, anyone wanting volume
⏱ Longevity: 750ml lasts 4-6 months with daily use
👍 Repurchase rate: High
Why Koreans Love This

Okay so the whole “Folligen” line from Dr.FORHAIR is literally everywhere in Seoul right now. Korean women swear by it for making their hair look fuller without that sticky, heavy feeling some volumizing shampoos give you.
This particular set is genius because you get the huge 750ml bottle PLUS two 100ml travel sizes. Perfect for testing it out before committing, or keeping one in your gym bag 💪
The formula is pretty unique too – it’s got this light green color and lathers really nicely without stripping your scalp. My hair feels clean but not squeaky or dry, you know?
What Real Buyers Are Saying
“I’ve been using this for 3 months and my roots actually have lift now! I used to need dry shampoo by noon but now my hair stays volumized all day. The scalp cooling sensation is really refreshing too.” — verified buyer
“My hair is super fine and flat, and this is the first shampoo that doesn’t weigh it down. The menthol tingle wakes me up in the morning lol. Fair warning though – if you have color-treated hair, use a good conditioner with it because it can be slightly drying on the ends.” — verified buyer

The cooling sensation people mention is real, btw! It’s from the menthol and feels super refreshing, especially in summer. But if you have a really sensitive scalp, test it on a small area first 🌿
| Feature | Details |
|---|---|
| Hair Type | Fine, thinning, oily scalp, flat hair |

| Longevity | 750ml lasts 4-6 months (daily use) |
| Best For | Anyone wanting thicker-looking hair without heavy residue |
💭 Mina’s Ingredient Note
I actually looked into the biotin and peptide complex they use here, and honestly it’s a decent concentration for a shampoo format – though you’d get better absorption from a leave-in treatment. The menthol does provide that scalp-stimulating effect people love, but if you’re dealing with actual hair loss, worth checking with a dermatologist first since this is more about volume than regrowth. The gentle cleansing agents are sulfate-free which is nice, but they do clean thoroughly so dry-haired folks might need extra conditioning.

Who Should (and Shouldn’t) Buy This

So here’s the thing – this shampoo is pretty targeted. It’s not trying to be everything to everyone, which I actually appreciate!
The people I know who love it most have fine or thinning hair that gets greasy at the roots but needs volume. If that’s you, this could be perfect.
💕 Is This For You?
✅ You have fine, flat hair that needs serious root lift
✅ Your scalp gets oily but your hair looks limp
✅ You love that tingly, cooling scalp feeling
✅ You want a salon-quality shampoo that actually lasts (this set is huge!)
❌ You have very dry, coarse, or bleached hair (might be too cleansing without a heavy conditioner)
❌ You’re super sensitive to menthol or fragrance
❌ You’re looking for intense moisturizing rather than volume
How It Compares to Other Bestsellers
| Product | Best For | Finish | Longevity | Buy |
|---|---|---|---|---|
| UNOVE Deep Damage Treatment | Damaged, dry hair | Silky, moisturized | 320ml set, 2-3 months | View |
| LABO-H Scalp Strengthening Shampoo | Scalp care, hair loss concerns | Clean scalp, strengthened roots | 750ml+600ml, 6+ months | View |
| Dr.FORHAIR Folligen Shampoo | Thinning, flat hair | Volumized, bouncy | 750ml+200ml, 5-6 months | View |
Honestly? If you’re choosing between scalp care shampoos, LABO-H is more medicinal-feeling while Dr.FORHAIR is more about that instant volume boost. UNOVE is totally different – that’s for damage repair, not volume 🤔
