2. Key Discussion Points and Insights

Chit Chat & Feedback (00:00–09:11)

• Valerie and Perry swap humorous travel and personal stories, including Perry's misadventures abroad and Valerie’s thoughts on the Super Bowl and new electronics.
• Listener Feedback:
  • A scientist from Pantene clarifies points about the Abundant & Strong hair care line, specifically about control formulas and clinical testing for hair retention.
    • [11:00] Valerie: “It’s hard when little bits of information are published here and there…and we just didn’t have all the data.”
    • Pantene used identical base formulas as a placebo, just omitting the actives.
    • They targeted both breakage and genuine hair retention from the root (not just breakage), adding credibility to their claims.
• Discussion on sulfates and how industry myths are perpetuated by marketing and salon culture rather than scientific evidence.

Hydrogen Peroxide-Free Hair Glosses (Melissa’s Question) [16:34–20:16]

• Main Question: Are there clear, colorless gloss products without peroxide? What’s the point of peroxide in colorless hair glosses?
• Answer:
  • The developer/peroxide in two-step gloss products (like Kristin Ess Signature Hair Gloss) isn’t for color or deep-acting benefits. It’s mainly used to turn the formula from liquid to gel for easy application.
  • It’s essentially an artifact of using the same base as their coloring products.
    • [18:40] Valerie: “The developer isn’t doing anything to the hair other than helping the product go from a liquid to…a gel so it doesn’t drip.”
  • Peroxide introduces light negative charges to the hair, which could help with deposition of conditioning agents, but it’s negligible for these glosses.
  • Using water would probably achieve a similar result.

Retinaldehyde vs. Adapalene for Anti-Aging (Tori’s Question) [21:18–29:29]

• Listener Tori asks: Is retinaldehyde better for anti-aging than Adapalene? Should I switch if I’m using OTC Differin (Adapalene)?
• Science Recap & Advice:
  • Retinoid overview:
    • Strongest options (tazarotene, tretinoin) require prescriptions.
    • Adapalene: engineered for anti-acne, OTC, less is known about its anti-aging benefits compared to retinoic acid/retinaldehyde.
    • Retinaldehyde: more evidence for anti-aging, milder than tretinoin, available in OTC products.
  • Limited evidence supports Adapalene’s effectiveness for wrinkle reduction; more robust data exists for retinoic acid and retinaldehyde.
    • [25:38] Valerie: “I can’t say either way… I would focus on what we do know. And what we do know is that retinoic acid and its precursor retinaldehyde do have some efficacy.” [26:46]
    • Perry references a small study where Adapalene and tretinoin performed similarly for wrinkles, but stresses more data is needed for Adapalene’s anti-aging benefits.
  • Practical advice: If acne is your main concern, stick with Adapalene; if anti-aging is the focus and you tolerate it, try retinaldehyde.

Terracotta Packaging (Amanda’s Question) [29:35–34:46]

• Listener Amanda asks: Is terracotta packaging (e.g., from Oquist Cosmetic) a good idea for skincare?
• Discussion:
  • Terracotta is eco-friendly (can return to earth), but comes with drawbacks:
    • Fragile—risks breaking in shipping or during bathroom use.
      • [31:12] Valerie: “If you drop this in your bathroom and cracks…you just kind of have to scoot it into your sink.”
    • Can be messy if chipped and wet (may stain surfaces).
    • Only suitable for waterless, oil-based, or solid products—can’t package water-based formulas.
    • “Recycling” the bottle means literally smashing it and putting in the soil (not practical for most consumers).
    • Ultimately, these containers are as much about art/branding as function.

Hair Hydration in Black Hair Care (Amina’s Question) [34:57–44:16]

• Listener Amina asks: Can you clarify the science around “hydrating” hair? What about oils vs. frequent washing and the goal of breakage reduction in Black hair care?
• Scientific Reality:
  • Terms like “hydration,” “hygral fatigue,” and “porosity” are generally imprecise or misused in consumer circles.
  • Hair “hydration” as consumers use it is a myth:
    • Scientifically, water acts as a plasticizer—makes hair soft/flexible when wet, but more water (especially from humidity) can cause frizz, roughness, tangling, and more breakage.
      • [39:54] Valerie: “Water content is actually the last thing that your hair wants.”
    • “Hydrating” products generally work by conditioning/lubricating the hair, not by adding water.
  • Oils and butters don’t “lock in moisture” so much as provide lubrication, which helps reduce breakage by lessening friction and stress on the hair fibers.
    • [43:33] Valerie: “The benefit of oils and butters is lubrication. And so when your hair is lubricated, you get less breakage.”
  • Frequent washing is more about scalp health and is not harmful as long as conditioning is adequate.
  • Key Takeaway: Focus on conditioning agents (silicones, oils, butters) that provide lubrication for less breakage.

Starting Your Own Skincare Line (Kelly’s Question) [44:36–52:17]

• Listener Kelly asks: How do I begin starting my own skincare line?
• Perry & Valerie’s Advice:
  • It’s easier than ever to launch a line thanks to digital marketing and e-commerce, but very challenging to stand out technologically.
    • Focus on having a unique story (Unique Selling Proposition, or USP)—what makes your line special?
      • [45:42] Perry: “…to stand out in this business is not really a technology thing. It’s more of a marketing story thing.”
    • Identify your target customer and make products for their needs/problems.
    • Don’t assume you need to formulate everything yourself—work with professionals for product development, compliance, and manufacturing so you can focus on marketing and storytelling.
      • [51:29] Perry: “Being a good chemist and formulator is a different skill set than being a good marketer and salesperson.”
    • Learn about industry regulations, labeling, claims testing, and be patient sourcing packaging—you don’t need to buy huge quantities to start.
    • Use professional resources and contracts with manufacturers to clarify responsibilities.
      • [49:16] Valerie: “Work with someone who is [aware of regulations]… Even if you’d like to go on Amazon or TikTok, shop… there are things that are required for you to do or provide or prove to make sure that your products have some of the basic information for the consumer from a safety perspective…”

3. Notable Quotes & Memorable Moments

• Valerie (re: product myths):
  [14:12] “I’m still surprised that there’s this sulfate conversation still going on because it’s so 30 years ago… sulfates are fine for your skin when formulated appropriately.”
• Perry (on consumer perception):
  [12:54] “I am just flabbergasted at how bad [consumers] are at noticing differences or how easily they’re tricked by what a fragrance is or what the packaging is, and they’re just not reliable.”
• Valerie (on hair hydration):
  [39:54] “Water content is actually the last thing that your hair wants. Because a consumer thinks hydration is their hair feels smooth, soft, it’s shiny, it’s lubricated. You can’t actually feel the cuticle. So the science world here differs a little bit from the real world.”
• Perry (on launching a brand):
  [45:42] “It’s more of a marketing story thing.” [52:17] “Being a good chemist and formulator is a different skill set than being a good marketer and salesperson.”
