There are actually quite a few reasons to go for a dip, however salt has been used historically in medicine for its healing properties and is a vital mineral for the human body.
It is not recommended to expose your hair to ocean water if you have recently treated your hair with chemicals such as dye or bleach. Treated hair has already been stripped of its nutrients and salt water will wick further moisture from the hair. Dyed hair can also begin to fade with excessive salt water exposure. You can get around this by first adding oil to your hair before entering the water.
The oil will shield your hair strands while allowing the scalp to benefit from the minerals. You can also use a moisturizer or deep conditioner to keep your hair hydrated and soft.
It’s important to wash your hair following salt water exposure, because if the salt remains in the hair for too long it will dry it out. If you’re planning on exposing your hair to ocean water, it’s recommended that you first use hair cream that contains SPF. While you’re in the ocean your hair is being exposed to a lot of UV rays. Using SPF cream in the hair helps prevent UV damage.
For those of us who do not live near salt water, there is luckily a convenient remedy that mimics the effects of a dip in the ocean. Mix two parts castile soap and three parts sea salt into a container and blend thoroughly. Wash your hair with this mixture for around 15 minutes and then rinse with cold water to eliminate the residue.
Alternatively, mix three tablespoons of sea salt with warm water and massage the scalp with it for 6-8 minutes. Rinse thoroughly with cold water afterward. Another homemade salt water treatment is created by first mixing 1 tbsp warm water and 1 tbsp sea salt into a spray bottle until the salt dissolves.
Next, add 1 tbsp coconut oil and 1 tbsp leave-in conditioner. To avoid developing follicle damage and rough hair, do not wash with these homemade solutions more than once a month.
