Do you want to know the secret to longer lasting hair weave and full lace wigs? MOISTURE, MOISTURE, MOISTURE!!
So how do you prevent your virgin hair weave and human hair full lace wigs from drying out after a few washes?
The reason most hair weave extensions dry out is because of use of chemicals, lack of moisture and using excessive heat. Think about it, we eat food to nourish our bodies with nutrients which eventually make their way to our hair and nails.
One of the easiest ways to get longer hair and nails is to eat foods and supplements that are rich with vitamins. Unfortunately, we can not feed our hair weave extensions the same way and we therefore have to use other means of “feeding” our virgin hair weave since they are 100% human hair. It is best to use organic and sulfate free shampoo and conditioners.
Remember that when you dye the hair, it goes through a chemical process so it is especially important to keep colored hair weave extensions and full lace wigs moisturized with a quality leave in conditioner.
Curly hair gets especially “thirsty” and is more likely to dry up and so it’s imperative to use a detangling and leave in conditioner on curly hair. From time to time, use a bit of extra virgin coconut oil to moisturize your hair. Virgin coconut oil is great because not only does it keep the hair moisturized and nourishes the hair, it also detangles the hair.
Products we recommends: After testing lots of products, one of the best conditioner we have found is the silicon mix conditioner and it comes highly recommended by hair stylists and salon owners.
Products to avoid: Avoid shampoo and conditioning products which use Sulfates, Isopropyl Alcohol, Formaldehyde and Propylene Glycol, these are strong chemicals which will strip the hair of natural oils and leave them dry.
