What pros are saying

“Today I attended the Line One Hair Master Class… a great reminder of why continuing education is so important in this industry. The more I grow as a stylist, the more I can bring back to the people who trust me with their hair.”

Common questions

Keratin Tip vs. Invisible Tape — which should I choose?

Keratin Tips are installed strand-by-strand for precision placement and maximum movement. Invisible Tape installs faster and is gentler on very fine hair, with a move-up every 6–8 weeks.

How long does a Genius Weft installation last?

The weft itself is built to be reused across multiple move-ups. Most clients return every 6–8 weeks to have the row moved up as their natural hair grows.

How do I match my shade?

Every shade is a rooted, true-to-life blend — the number tells you the level, the name tells you the tone. For a guaranteed match, order the Color Book and compare real hair swatches in your own light.
