I'M BACK, I'VE MISSED YOU… AND I'VE GOT A FEW QUESTIONS ABOUT HAIR SCIENCE!

EPISODE 27

(STANDARD)

Captain Color is back behind the microphone!

After several months of recovery, research, and writing, Dennis Gebhart returns to Guru In Your Ear with some interesting questions about the direction of professional hair education.

Have three-minute social media videos created a new generation of instant science experts? What does bond repair actually mean? And when products promise to rebuild or restore damaged hair, how do we distinguish measurable improvements from claims about molecular chemistry?

From K18 and Olaplex to the difference between cosmetic results and scientific evidence, this episode challenges us to ask better questions, examine the research, and recognize the difference between knowing scientific terminology and genuinely understanding the science.

Because knowing the words isn't the same as understanding the science.
