Experiencing the allure of the ocean or sea on a hot summer day can be invigorating, but the salt water that gives the sea its characteristic taste and buoyancy may not be as kind to your hair. While salt water can provide a refreshing escape, its effects on hair health are often underestimated.
In what ways can salt be harmful to your hair?
Moisture Stripping
Salt water acts as a natural desiccant, sapping moisture from the hair shaft and leaving it dehydrated and brittle. Repeated exposure strips away the natural oils that keep hair supple and hydrated, resulting in a dry, straw-like texture. This moisture depletion weakens the hair’s internal structure, making it more prone to breakage, split ends, and overall dullness.
Cuticle Damage
Salt water’s abrasive nature can wreak havoc on the hair’s outer protective layer, the cuticle. High concentrations of salt can roughen the cuticle surface, raising and jagging it. This compromised barrier leaves the inner layers of the hair vulnerable to damage from environmental stressors like UV radiation, pollution, and chemical exposure. As a result, the hair becomes prone to frizz, split ends, and a lackluster appearance.
Color Fading
For individuals with dyed or chemically treated hair, salt water poses a significant threat to color longevity. Seawater’s salt content penetrates the hair shaft, breaking down the bonds that hold color molecules in place. As these molecules are leached out, the hair color fades, losing its vibrancy and richness over time.
Scalp Irritation
Salt water’s abrasive nature can irritate the scalp, especially for those with sensitive skin or pre-existing scalp conditions. The salt crystals can cause microscopic tears in the scalp’s delicate tissue, leading to redness, itching, and flakiness. Individuals with conditions like eczema or psoriasis may experience exacerbated symptoms after exposure to salt water, further compromising scalp health and comfort.
Tangled Hair
Salt water has a knack for transforming smooth, manageable locks into a tangled mess, especially for individuals with longer or finer hair. Seawater’s high salinity disrupts the hair’s natural alignment, causing individual strands to stick together and form knots. Untangling these knots can be a laborious and damaging process, leading to hair breakage, split ends, and increased hair loss over time.
