Ice Extensions fully customized to your goal, base density, hair strength, and target length. Natural, believable volume typically lands at 130–150 capsules. For 24 inches and longer with dense ends, plan at least 160–170 so the perimeter stays present. At 20 inches, about 130 can be exactly right. For new clients we start light to keep the base comfortable and the blend clean. At 3–4 months we reassess and add only if your hair carried the weight well—especially on fine hair and sensitive scalp
