Hi, I'm Perry and you're listening to The Beauty Brains.

Hello and welcome to the Beauty Brains, a show where real cosmetic chemists answer your beauty product questions and give you an insider's look at the

cosmetic industry. This is episode 403. I'm your host Perry Romanovski and I'm not solo today because

Valerie George is back. Hello Valerie. Hi Perry. You know since Valerie is still taking care of the little

one, we're going to make this a slightly shorter episode, but we will be covering

some of your questions that we have a big backlog, so we'll get to those in the next show, but

we got a bunch here today. And those include, does product buildup cause breakage in hair,

is a chemical exfoliant better than a soft silicone scrubber? What are your thoughts about beef tallow

facial creams and are rinse-free shampoos any good? But first, Valerie, you're back.

It's just been, it's less than a month, but you're back. Yeah, it's a few weeks, but,

you know, I missed you guys. And so I said, let's come back. I had a

baby boy, baby C, we'll call him. And he's so sweet. He hardly cries. Hardly, meaning I've only

ever heard him cry once. And that was because I actually accidentally bopped him on the head.

Wow.

Wait, you're not going to call him baby cosmetic chemist?

Well, that's what Baby C is short for.

Oh, good.

Gotcha, baby C.

Exactly.

Yeah, yeah.

But he's the sweetest thing.

He's so kind.
