Dr.FORHAIR Shampoos

The Phytofresh Shampoo (500ml) and Phytofresh Oily Shampoo (70ml and 500ml+70ml set) are Dr.FORHAIR's most targeted oil-control options. The "oily" variant uses a stronger sebum-balancing complex and is popular for people who find their scalp gets greasy within 24 hours of washing. The standard Phytofresh is slightly gentler - good for oily scalps that also deal with sensitivity or flaking.

The 70ml size is useful for travel or for people who want to trial the formula before committing to a full bottle. The 500ml+70ml bundle is a practical buy if you already know it works for you.

Polyzen is Dr.FORHAIR's broadest line and comes in several sub-variants. The base Polyzen Shampoo (available in 500ml+200ml and 750ml) is designed for normal to slightly oily scalps and emphasizes scalp balance without stripping natural moisture. It's the most versatile pick in the lineup and tends to suit people who don't have a strong directional concern.

Polyzen Plus (750ml) steps up the formula with additional scalp-nourishing actives - useful if you're dealing with mild thinning, stress-related shedding, or want a more comprehensive daily treatment in one step. Both Polyzen and Polyzen Plus are available in large sizes, which makes them cost-effective for daily use.

Polyzen Silk (300ml and 500ml) adds a silk-protein complex to the Polyzen base. This targets hair texture rather than scalp condition - it's designed for people with coarse, frizzy, or chemically treated hair who want a softer finish without a heavy coating. The 300ml is a good entry size if you're transitioning from a different brand and want to compare texture over 4-6 weeks.

It's worth noting that silk proteins in shampoo are rinsed off quickly, so the benefit is more about moisture retention during washing than long-term protein treatment. If you need deeper protein repair, a leave-in treatment would complement this.

The Polysene Plus Shampoo (500ml) sits somewhat apart from the Polyzen family in name but shares the same scalp-first philosophy. It uses a denser active concentration and is suited for people with persistent scalp concerns - think chronic buildup, sensitivity cycles, or mild seborrheic tendencies. Because the formula is richer, a small amount goes a long way, and many users find a 500ml bottle lasts longer than expected.

It works best when left on the scalp for 1-2 minutes before rinsing, giving the actives time to do more than just clean.

The Phytotherapy Shampoo (500ml) is Dr.FORHAIR's most ingredient-forward formula, drawing on a range of botanical extracts aimed at restoring scalp barrier function. It's typically recommended for scalps that have been stressed by heat styling, color treatments, or harsh water. The plant actives include extracts that support circulation and reduce scalp inflammation at a low level.

This is the line most often recommended for people who've been using strong anti-dandruff shampoos (like those with zinc pyrithione or selenium sulfide) and want to step down to something gentler without losing scalp control entirely.

A quick decision framework: if your main complaint is oiliness or limp roots, start with Phytofresh Oily Shampoo. If you want a well-rounded daily shampoo without a specific complaint, Polyzen or Polyzen Plus covers most scalp types. If frizz or chemical damage is your bigger concern, Polyzen Silk addresses the hair shaft rather than just the scalp. For ongoing scalp sensitivity or buildup cycles, Polysene Plus or Phytotherapy are the stronger choices.

Dr.FORHAIR doesn't manufacture color-safe shampoos as a separate SKU - Polyzen Silk and Phytotherapy are generally the safest bets for color-treated hair due to their lower surfactant intensity.

Dr.FORHAIR consistently offers multiple sizes across their lineup, which is useful for budgeting. The 70ml format (Phytofresh Oily) is a travel size or trial size. The 300ml format (Polyzen Silk) is a one-month supply for most users washing daily. The 500ml sizes are the standard workhorse bottles, and the 750ml options (Polyzen, Polyzen Plus) are the best value per ml if you're buying for a household.

The bundle packs (like 500ml+200ml or 500ml+70ml) are typically priced to make the add-on size effectively free or near-free - worth choosing over the standalone 500ml if you travel or want a backup.

Korean hair care brands tend to treat shampoo as a scalp treatment rather than just a cleanser, and Dr.FORHAIR leans hard into that framing. Compared to brands like Ryo (more herbal, more traditional Korean medicine influence) or Mise-en-scène (more salon-style glossing), Dr.FORHAIR sits in the science-meets-botanical middle ground - heavier on clinical claims than Ryo's herbal heritage but less focused on post-wash shine aesthetics than Mise-en-scène.

The brand is widely available in Korean pharmacies and H&M Beauty outlets, which gives it a reputation for being accessible and daily-use rather than a prestige pick. That positioning shows in the pricing and the practical size range.

For scalp-targeted shampoos like these, the technique matters as much as the product. Apply the shampoo directly to a wet scalp (not just the hair) and massage in small circular motions for at least 60 seconds before lathering through the lengths. Let the formula sit for 1-2 minutes if you're using Polysene Plus or Phytotherapy - these benefit from contact time. Rinse thoroughly; residue from any shampoo can cause scalp congestion over time.

If you're switching to Dr.FORHAIR from a silicone-heavy shampoo, expect a 1-2 week adjustment period where hair may feel different as the silicone buildup washes out. This is normal and not a sign the product isn't working.
