Hello, identify the area where you want to place the buckle. Even if you have thin hair, you can use a tiny strand or the area close to the scalp as a base to help the clip hold better. When attaching our snap clips, position the clip at the base of your hair with the clip fully "open," then close it until you hear a "click." This allows the clip to gently hold onto the scalp. You can also type "how to put on a hairless baby hair clip" into a search engine for detailed images. Thanks for your interest.
