research Allergens of permanent hair dyes induces epidermal damage, skin barrier loss and IL-1 α increase in epidermal in vitro model
Permanent hair dye mixtures can irritate and damage the skin.
research Hydrogen Peroxide and Wound Healing
Hydrogen peroxide may have both positive and negative effects on wound healing, and its safe concentration for hair transplant surgery is unclear.
research ABSENCE OF H2O2 BREAKDOWN IN HUMAN HAIR MEDULLA IMPLICATIONS IN FOLLICULAR MELANOGENESIS
Human hair medulla doesn't break down hydrogen peroxide, which may affect hair color formation.
research Volume Changes During Water Binding to Hair Fibers
Hair increases in size when it absorbs water, and treatments like bleaching affect how much water it can take in.
research Damage limitation: comparing the impact of polymers on bleached hair, when applied within or as post-bleach treatments
Polymers help reduce damage and improve bleached hair when used during or after bleaching.
research A Study on Hair Damage Following the Change of Treating Treatment Procedure when Iron Permanent is Treated
Applying conditioner mid-treatment reduces hair damage during perms.
research J. Cosmet. Sci., 59, 203-215 (May/June 2008) �Effects of permanent waving on changes of protein and physicomorphological properties in human head hair
