While a good spray in detangler can help, it's always best to try and discover the cause of the recurring snarls and to restore moisture to your strand to prevent tangles from continuing in the future.
There can be many reasons for your hair being snarly ranging from, but not necessarily including:
- Overuse of chemicals (color, texturing products)
- Excessive use of hot tools ranging from hot blow dryers to irons and curlers
- Dietary deficiencies including lack of hair enriching vitamins and natural oils
- Washing hair in hot water
- Using full strength shampoo products which strip hair of natural oils
- Well water or water supply high in oil stripping chemicals
- Overexposure to sun, wind or related environment toxins
- Smoking or exposure to smoke on a regular basis
- Hormonal imbalances
- Going out in the sun without keeping hair covered
- Sleeping on cotton pillowcases or bedsheets which rough up the cuticle.
- Using brushes and/or combs with sharp bristles.
- Wearing hair accessories which tangle the hair.
- Improper detangling
I would suggest you wash hair in lukewarm water and consider using a hydrating shampoo which you have diluted with 1/4th teaspoon of shampoo in a clean gallon jug and shaken to form a suds. Get hair saturated with water and then dizzle the suds from the roots down to the ends. Pat the suds into the wet hair to help loosen dirt and/or toxins.
Rinse well and apply a rinse-out conditioner which is rich in hydrating properties. Allow to remain on the hair for up to 5 minutes. Detangle hair from the ends to the roots using fingers and/or detangling comb while the conditioner is still in the hair.
Once hair is detangled, rinse well with lukewarm water finishing with a cool/cold water final rinse.
Towel blot. Apply a light leave-in conditioning detangler of your choice. Aveda makes a great light detangler. If you prefer, you can take a little of your favorite leave-in conditioner and combine in a spritzer bottle with lukewarm water to make your own formula.
Spray damp hair.
When possible, allow hair to air dry.
This should go a long way to improving your snarls.
