• Myth: Trimming will make your hair grow stronger, longer, faster or thicker. Since hair is dead, cutting the ends has no effect on what happens at the scalp.

Strands will grow at the same predetermined rate each month, and individual strands will grow in at the same thickness as before. While trimming or cutting the hair does seem to give the appearance of thicker hair, this is only because all of the freshly trimmed hairs now have the same, clear endpoint.
