PU (Polyurethane) extensions are made by bonding hair into a thin, flexible silicone-like strip. This makes them 50% thinner and much more discreet.\u003cbr\u003e\u003cstrong\u003eQ: Can I use heat tools on these extensions?\u003c\/strong\u003e\u003cbr\u003eA: Absolutely. Since these are 100% Virgin human hair, you can curl, straighten, and blow-dry them just like your own hair. We recommend using a heat protectant to maintain longevity.\u003cbr\u003e\u003cstrong\u003eQ: Will the clips slip out during the day?\u003c\/strong\u003e\u003cbr\u003eA: No. We use premium silicone-lined stainless steel clips. The silicone provides a soft grip that prevents slipping while protecting your natural hair from friction.\u003cbr\u003e\u003cstrong\u003eQ: How do I choose the right length?\u003c\/strong\u003e\u003cbr\u003eA: For a natural look, choose a length within 2-4 inches of your own hair. If you want a dramatic change, our 7-piece set provides enough density to blend long extensions even with shorter hair.\u003cbr\u003e\u003cstrong\u003eQ: Are these comfortable for all-day wear?\u003c\/strong\u003e\u003cbr\u003eA: Yes. The PU weft is breathable and incredibly lightweight. Most users report forgetting they are even wearing them after just a few minutes.\u003cbr\u003e\u003cstrong\u003eQ: How long does a set of UIHAIR extensions last?\u003c\/strong\u003e\u003cbr\u003eA: With proper care (sulfate-free washing and air drying), our extensions typically last 12-18 months depending on the frequency of wear.\u003c\/p\u003e","brand":"UIHAIR","offers":[{"title":"#1 \/ 14
