IN EVERY STRAND

THE ONLY HAIR EXTENSIONS BACKED BY REAL,
UNDENIABLE DATA — NOT UNSUBSTANTIATED CLAIMS.

PROLONGED HAIR
CHANGES THE GAME.
The hair extension space is saturated with empty promises and marketing jargon—claims that don’t stand up to scrutiny. At Prolonged Hair, we do things differently.
We are the only brand in the category that invests in third-party, independent lab studies—and we publish every result, without exception. No filters. No selective data. Just proof.
Because when your product performs at the highest level, transparency isn’t a risk. It’s the standard.

DON'T JUST TAKE OUR WORD FOR IT
SEE THE DATA YOURSELF
The difference? Other brands hide their lab results—we showcase ours.
