Bleaching the knots and or lace helps them blend into the color of your scalp by removing the black dots. Mix equal parts bleach and 20 to 30 volume professional developer in a bowl. Then, turn the wig inside out. Use the applicator brush that came with the bleach to carefully apply the bleach to the lace and knots. Wait about 15 minutes or until the knots turn blonde, then thoroughly rinse the wig out upside down. Immediately wash the wig with a neutralizing shampoo to stop the chemical process. Then, condition the wig to prevent the material from getting dried out. Allow the wig to air dry. Bleaching the knots will conceal the appearance of the black dots on the lace. Bleaching the knots isn't only for lighter skin tones. Bleaching should be effective for any skin tone. If the lace doesn't quite blend in with your scalp or forehead, you can use concealer to color it. Take a concealer that closely matches your skin tone and apply a small amount of it onto a sponge. Use the sponge to blend the concealer into the lace front until it matches your skin tone. Heat styling tools are typically okay to use on real human hair. You can use a flat iron or curling iron to style your hair as desired. Use a low heat setting and only style dry hair so that you don't cause excess damage to the wig. To straighten the wig, take a 1 inch (2.5cm) section of hair and run the heated flat iron from root to tip. Repeat on each section until you've straightened all of the hair on the wig. To curl the wig, clamp the curling down on a 1 inch (2.5cm) section of hair in the middle (between roots and tips). Then, wrap the bottom section of hair around the wand. Hold for 5 to 10 seconds and then let go. Repeat on each section until all of the hair has been curled. If you don't want to leave the hair down, you can put it up in a ponytail or bun. Make a side ponytail by creating a deep part, then brush all of the hair to 1 side. Gather all of the loose hair and secure it with a ponytail holder. Create a top knot by gathering the hair into a high ponytail. Then, twist all of the hair around into a knot. You can secure the bun with bobby pins or a ponytail holder. Make sure the wig looks natural at the nape of your neck.

Summary:
Bleach the knots or lace on your wig to hide them. Camouflage the lace on the wig with concealer. Use heat styling tools only on human hair wigs. Style the wig in an updo, if desired.
