WHAT IS THE SCALP SKIN BARRIER AND WHY IS IT IMPORTANT?
Skin plays a vital role in the protection from the external environment, including oxidative stressors, allergens, pathogens and irritants, while serving as a thermal regulator for the body. The scalp barrier consists of the skin layers (the dermis and epidermis), the scalp micro-biome, and a higher than average level of sebaceous lipids. All of these parts play important roles in the scalp's health.
We could say that the scalp’s skin, sebum layer, and micro-biome constitute a closely interconnected protector for the body and “fertile soil” for healthy hair growth.
The scalp however, can become compromised with age and through exposure to environmental assaults such as ozone, UV and other oxidizing and irritating molecules.
Proper care of the scalp is important to minimize exposure to these irritating, pro-inflammatory molecules that can build-up over time, while also ensuring the maintenance of the scalp barriers integrity, a balanced sebum production and ideal conditions for long, strong, healthy hair growth.
Antioxidants and barrier supporting botanicals can play an essential role in reducing damage, especially as endogenous defenses decrease with age or become overwhelmed from environmental damage.
WHAT DAMAGES THE SCALP?
The impairment of the scalp barrier is associated with increased irritation, scalp dryness, and itchiness. To maintain a healthy scalp the barrier’s integrity is vital.
• A gaseous pollutant, found indoors and outdoors, causes the oxidation of unsaturated lipids found on the scalp.
• Depletes the naturally occurring antioxidants on the scalp.
• Stimulates a cascade of pro-inflammatory events which, if prolonged, can cause damage to the barrier and scalp skin itself.
2. Microbial metabolites
• Metabolize and release free fatty acids, such as oleic acid, which can lead to inflammation, itching, and flaking of the scalp.
• Causes oxidation of lipids and other metabolites that are damaging to cells.
3. UV radiation
• Low doses (below doses that cause skin redness) of UVA have shown to generate damaging lipid metabolites.
4. Oxidative stress
• The skin & hair follicle is a highly oxidative environment (endogenous stress).
• Antioxidant defenses decrease as we age.
• Other pollutants, not listed above, particularly volatile molecules that can reach the scalp can induce oxidative stress and deplete endogenous antioxidants.
