Does Red Hair Need Different Care? Your Beauty Questions Answered - episode 436

Saturday, October 31, 2026 • Duration 53:11

Send us Fan Mail

On today’s show we cover lots of questions including…

Are eye masks and eye creams worth using, and where does castor oil fit in?
How can you replace discontinued exfoliating wipes?
Can a spray replace a moisturizer, and can you find a fragrance-free alternative to a conditioner you love?
What evidence should you look for when comparing scalp serums?
Does red hair call for different skin and hair products?

Katie and Nikki join us through their recorded questions this week. We talk through finding a replacement for a much-loved wipe, what moisturizers need to do beyond adding water, and why comparing scalp-serum marketing claims can be tricky. We also discuss eye-area products, fragrance preferences and the questions still open about red hair and skin.

Beauty News

Jennifer Lawrence’s announced hair-care brand, followed by a discussion of NAD+ skin care, formulation challenges and the evidence for niacinamide.
