Some SMP results may be difficult to notice in ordinary situations, but no procedure can be guaranteed undetectable. Visibility depends on pigment contrast, treatment design, existing hair, lighting, viewing distance, and the observer. A shaved-head result presents differently from density camouflage beneath longer hair. Someone examining your scalp closely may notice details that are less apparent during normal conversation. The useful goal is a suitable, realistic cosmetic appearance—not a promise that every person, in every setting, will assume the pigment is real hair.
What You Should Know
- Ordinary social viewing and close scalp inspection are different tests of appearance.
- Existing hair can contribute to camouflage but does not make detection impossible.
- An observer's perception is one reason invisibility cannot be guaranteed.
When to Seek Professional Advice
Discuss the situations that matter to you—conversation, close contact, work, or photographs—and ask to evaluate the proposed appearance without relying on an undetectability promise.
