AMMONIUM HYDROXIDE
Is AMMONIUM HYDROXIDE safe for seborrheic dermatitis?
Ammonium Hydroxide is context-dependent for seborrheic dermatitis because concentration and final product pH are more important than its name alone. It is used to adjust formulas or support hair processing, not to treat seb derm.
No applicable exact-ingredient human seb derm or Malassezia study was found. In a properly formulated product only the finished exposure can be assessed, while concentrated or strongly alkaline products may irritate already-inflamed skin. Follow directions and do not use a product that causes sustained burning.

What is AMMONIUM HYDROXIDE used for in skincare?
Ammonium Hydroxide is ammonia dissolved in water and used as an alkaline pH adjuster. It can help a formula reach the pH needed for stability or, in hair products, open the hair structure for colouring or processing. Its effect depends heavily on concentration, ventilation, contact time and the finished formula.
