Step 1: Lay out your extensions, or "wefts," on a flat surface, grouping together like sizes.
Step 2: Part your hair wherever you would normally.
Step 3: Section off hair perpendicularly from your part down to your ear.
Step 4: Use a hair clip to hold the section in place.
Step 5: Repeat steps 2–3 on the opposite side of your head.
Step 6: At the back of your head, section off the bottom inch of hair and clip up the rest of your hair.
Step 7: Select the weft of hair that will best fit the section. You will continue to do this for each section.
Step 8: Use small hair elastics to create sections of hair the same distance apart as the extension clips.
Step 9: Open up the clips on the first weft.
Step 10: Secure the weft clip on top of the elastic and snap closed.
Step 11: Once all clips are snapped closed, smooth out the hair with your fingers or a brush.
Step 12: About half an inch up from the first weft, create the next section of hair.
Step 13: Use small hair elastics to create sections of hair the same distance apart as the clips on the weft.
Step 14: Secure each weft clip on top of the corresponding elastic and snap closed.
Step 15: Once each clip is closed, smooth out hair with fingers or a brush.
Step 16: Create the next section half an inch above the last and put in the small elastics.
Step 17: Snap each extension clip closed on each elastic and smooth out your hair with fingers or a brush.
Step 18: Create the next section half an inch above the last and put in the small elastics.
Step 19: Snap each clip closed on the elastics and smooth hair with fingers or a brush.
Step 20: If you parted your hair on the side, create the next section toward the side with the most hair — not directly in the middle of your head.
Step 21: Snap each extension clip closed on the elastics and smooth hair with fingers or a brush.
Step 22: Create the next section of hair on the side of the head with more hair, about half an inch above the weft.
Step 23 : Use one hair elastic and an extension weft with a single clip.
Step 24: Snap the clip closed and smooth the hair with fingers or a brush.
Step 25: On the side of your part with less hair, use one hair elastic for an extension weft with one clip.
Step 26: Snap the clip closed and smooth hair with fingers or a brush. Take down the rest of your hair and style as desired.
How To Wash Clip-In Hair Extensions
*Note: Only use shampoo and conditioner on extensions made of real human hair.
• Remove hair extensions from your head.
• Use a wide-tooth comb to remove all knots and tangles from extensions.
• With lukewarm water, gradually wet hair, combing as you moisten the hair to keep it from becoming tangled.
• Using a sulfate-free shampoo, wash the extensions from the top down.
• Rinse thoroughly with lukewarm water, moving from the top down.
• Apply a lightweight conditioner, using more toward the ends of the hair and less toward the top.
• Wrap hair in a towel and gently press out the excess water.
• Comb through the extensions with a wide-tooth comb. Air dry.
