A Brazilian weave, also referred to as a Brazilian wave, utilizes 100-percent virgin Brazilian hair to create a soft, wavy style. A stylist can apply Brazilian hair in any weave technique you prefer, allowing you the freedom of choice. However, when a stylist states that she offers a Brazilian weave, she may also be referring to a technique known as the Brazilian knot, where the extension is bound to the hair in small sections using an elastic thread. Taking care of a Brazilian weave is similar to any other human hair weave, but there are a few minor considerations when taking care of Brazilian hair and the Brazilian knot in particular.
Wash your hair every one to two weeks. Because the hair is not attached to your scalp, it does not receive the protection or moisturizing effects of the natural oils. If you have an extremely oily scalp, consider using a dry shampoo at your roots between washings.
Use a mild shampoo and work slowly from the scalp to the tip. Do not rub your hair or pile it on top of your head to wash it.
Wash near the scalp and give yourself a light massage to protect the natural hair from bacterial growth and stimulate blood flow. The Brazilian knot allows greater freedom to work next to the scalp, so do not neglect a gentle but thorough scrub.
Apply a moisturizing conditioner after every shampoo and a deep conditioner every two to four weeks. Because the Brazilian weave is made from natural human hair, it will respond to deep conditioning, repairing the cuticle and restoring smoothness and shine.
Blot, but don't rub, your hair dry and allow it to air dry whenever possible. The Brazilian weave is prized for its natural, soft wave that will bounce back after washing with little or no hair product.
Use hair products as desired. However, avoid product buildup whenever possible. Using harsh shampoos will strip the weave of its natural moisture, leaving the hair brittle and dry.
Comb out the hair from root to tip with a wide-toothed comb or a hair extension loop brush. If you choose to have the Brazilian knot technique applied as well, you may work close to the scalp because of the extremely small sections of hair. However, work gently and work in small sections to remove difficult snags near the scalp.
Style hair as desired. Heat style sparingly to avoid damaging the hair, but the Brazilian hair will straighten with a blow drier or curl with rollers or a curling iron.
If you want a straight look, do not choose a Brazilian weave. The natural wave will have to be blown out for the duration of the weave or permanently straightened, both of which will damage the weave and shorten its lifespan.
