Episode notes
Why Peroxide Appears In Colorless Hair Glosses
- Use a developer only when the formula requires it to gel or activate; water could often replace the peroxide developer in a colorless gloss.
- Don't assume the peroxide forces conditioning agents into hair; it mainly thickens the product and slightly changes fiber charge.
Match Retinoid To Your Skin Goal
- Retinoids differ in receptors, stability, and irritation, so choice depends on goal and tolerance.
- For anti-aging, Valerie prefers retinaldehyde/tretinoin evidence, while adapalene shows some promising but less-studied results.
Try Retinaldehyde If Tretinoin Is Too Harsh
- If tretinoin causes too much irritation, try retinaldehyde as a gentler OTC alternative for anti-aging.
- Expect retinaldehyde to be somewhat less irritating and potentially more effective than retinol for wrinkles.
