Dr.FORHAIR's three Korean 500 mL shampoos: Thickening vs BIO-3 vs PhytoTherapy

Five practical checks to distinguish three current Korean shampoo listings and wash the scalp gently.

As checked in October 2026, Korean haircare brand Dr.FORHAIR separately lists Folligen Thickening Shampoo 500 mL, BIO-3 Hair Loss Symptom Care Shampoo 500 mL, and PhytoTherapy Scalp Care Shampoo 500 mL on its Korean store. The brand markets these toward fine-hair volume, reduced hair-shedding symptoms, and care for a sensitive scalp, respectively. Those are product positioning claims, not independent evidence that a shampoo diagnoses a cause of hair loss, cures baldness, or regrows hair. The American Academy of Dermatology (AAD) recommends cleansing the scalp rather than harshly rubbing shampoo along the whole hair shaft and adapting wash frequency to the hair and scalp. A DADA Studio video from July 2019 is explicitly native advertising for **older** Dr.FORHAIR products. It is historical context, not a demonstration or test of the 2026 Thickening or BIO-3 formulas.

  1. 01

    Read the full current 500 mL product label

    Folligen Thickening, BIO-3 Hair Loss Symptom Care, and PhytoTherapy Scalp Care are distinct 500 mL Korean store listings. Do not assume an old video saying only 'Folligen shampoo' depicts the current Thickening product or formula.

  2. 02

    Separate the marketing categories from medical needs

    Brand categories mention fine hair and volume, hair-shedding symptoms, and sensitive scalps. Check your actual ingredients and tolerance; a cosmetic hair-loss symptom claim does not diagnose or cure the underlying cause of hair loss.

  3. 03

    Focus shampoo on the scalp and wash gently

    AAD advises working shampoo mainly over the scalp to remove buildup and excess oil while avoiding unnecessary friction along the full hair length. Use fingertips gently. Follow your purchased bottle for the quantity and any specific contact or rinse directions.

  4. 04

    Rinse well and condition the hair as needed

    Rinse shampoo thoroughly and use conditioner if it suits your hair. According to AAD, people with fine or straight hair may focus conditioner on the ends, while dry or curly hair may benefit from application along more of the length. Matching the shampoo brand is not required.

  5. 05

    Adjust washing to oiliness and watch for symptoms

    Oily scalps may need more frequent washing; dry or textured hair may need less. Stop if a product leads to itching, rash or burning. For persistent or sudden hair loss, seek a dermatologist's assessment instead of depending on shampoo advertising.

✦ Helpful tips

  • The 2019 DADA Studio paid promotional video shows historical brand products, not independently verified 2026 formulas.
  • The listed names and sizes describe the Korean market; do not presume the same ingredients, claims, availability or pricing in Japan, the U.S. or elsewhere.

ⓘ Keep in mind

  • Hair-loss symptom care marketing does not establish that these shampoos treat every cause of alopecia or reliably regrow hair.
  • Stop using irritating products and consult a clinician for continuing hair loss, scalp inflammation or pain.
