Audience Questions and Expert Answers

1. Curl Cream Consistency Change (Question from Renata)

Question: Renata from Sao Paulo reports that her curl cream from Alpha Parf Alta Moda has become watery despite having an expiration date of 2028. She seeks advice on whether the product has gone bad.

Answer: Perry and Valerie explain that the thinning of the cream is likely due to temperature fluctuations causing syneresis, where water separates from the emulsion. They suggest shaking the product before use and storing it in a cooler, more stable environment to prevent further separation. They assure that as long as there are no changes in color or odor, the product remains safe to use.

Valerie George [19:07]: "So what could be happening? ... it might not work for you."

Notable Quote:

Valerie George [20:45]: "But if you notice a performance difference, I would just toss it."

2. Retinol vs. Tretinoin Efficacy (Question from Lisa)

Question: Lisa asks whether the lasting results of retinol are comparable to tretinoin (Retin A), considering that tretinoin is more potent but also more irritating.

Answer: Valerie elaborates that while retinol must convert to retinoic acid within the skin, tretinoin provides immediate efficacy as it is already in the active form. Tretinoin tends to offer more noticeable results but comes with increased skin irritation. They conclude that the choice depends on the user's tolerance and desired outcomes, with tretinoin being the gold standard for efficacy.

Valerie George [24:58]: "Tretinoin is the gold standard. It's what is tested against."

Notable Quote:

Perry Romanowski [25:11]: "Once you stop using either of them, your skin is going to kind of revert back to how it naturally was."

3. Pantene vs. Davines Shampoo for Bleached Hair (Question from Lorena)

Question: Lorena wonders if Pantene is suitable for her bleached hair or if she should switch to the more expensive Davines Volu shampoo as recommended by her new hairdresser.

Answer: Valerie and Perry address the misconception that Pantene strips hair. They analyze the ingredient lists, noting that both shampoos contain similar conditioning agents. They explain that the primary difference lies in the cleansing agents used, with Davines employing sodium lauroyl methyl isethionate, which may leave more residue compared to Pantene's formulation. They reassure Lorena that Pantene is a moisturizing option and that expensive alternatives are not necessarily superior.

Valerie George [29:05]: "It's not that it's better for your hair, it's just different."

Notable Quote:

Perry Romanowski [30:02]: "It's a moisturizing shampoo. It's practically a two in one."

4. Using Skincare Products on the Scalp (Question from Rita)

Question: Rita asks whether it's safe to apply skin moisturizers, specifically the Hadalabo toner, on her scalp.

Answer: Valerie emphasizes that while the scalp is indeed skin, it has unique needs distinct from facial or body skin. She approves of the Hadalabo toner for scalp use, highlighting its simple formulation with humectants like butylene glycol and glycerin, which are beneficial for scalp hydration without harmful exfoliants.

Valerie George [36:34]: "This formula is actually perfect for scalp. It doesn't have any of the things that I think violate, you know, scalp health principles."

5. Using Metal Spoons to Mix Vitamin C (Question from Paula)

Question: Paula inquires about the safety of using a stainless steel spoon to mix ascorbic acid with water for skin application, concerned that metal might adversely affect the vitamin C.

Answer: Perry clarifies that high-quality stainless steel is resistant to corrosion and should not significantly affect the ascorbic acid. Valerie adds that while stainless steel is generally safe, household metal utensils may not always be of the highest quality. She suggests using plastic spoons to avoid potential metal ion contamination and recommends monitoring the pH of the mixture to ensure skin safety.

Valerie George [43:04]: "You don't want to put something on your skin that's like a PH of one either."

Notable Quote:

Perry Romanowski [40:31]: "So stainless steel, we use that in manufacturing stuff because it's pretty resistant to any kind of corrosion."

6. Safety and Effectiveness of Salt Sprays for Hair (Question from Morgan)

Question: Morgan asks whether salt sprays are safe for hair use, how they work, and if there are any alternatives.

Answer: Valerie explains that salt sprays typically contain salts like magnesium sulfate, which recrystallize on the hair after application to lock in styles without causing damage. Perry concurs, noting that the salts used are large and do not penetrate the hair fibers, making them safe when used correctly. They also discuss the trend of incorporating magnesium from the DIY beauty community into commercial products.

Valerie George [43:27]: "I think they're actually really great products. They're really harmless."

Notable Quote:

Perry Romanowski [46:19]: "Salt sprays like she said, it's just topical. It's not penetrating."
