Does More Lather Mean Cleaner Hair? | Ask Obia, Episode 3

The foam in your shampoo is not doing what you think it’s doing.

Big lather, big clean. No lather, “is this even working?” We were all trained the same way. So in Episode 3 of Ask Obia I show you what a cleanser actually does, why foam isn’t it, and how I build a shampoo bar.

The matchstick

Every cleanser is one kind of molecule: a surfactant. Picture a matchstick. The head loves water, the tail loves oil. Wet your hair and thousands of them dive tail-first into the oil on your scalp, roll it into a ball, and the ball rinses away. That’s clean. No bubbles required.

Where foam comes from

Foam is the same molecules wrapped around air instead of oil. A side effect. It isn’t touching the dirt; the molecules are. A mountain of lather can leave a scalp barely cleaner, and a quiet lather can leave it clean.

Biggest foam, strongest strip

The biggest foam comes from the strongest surfactants: sulfates. They strip everything, including the oil your scalp made on purpose. On curls that oil barely travels down the coil anyway. Dry, frizzy, tight scalp, and then you buy more product to fix what the sulfates did.

What “sulfate-free” means

A gentler surfactant. It still grabs the dirt, and it leaves the coat your scalp needs. A quieter lather isn’t the product failing. It’s the product not overdoing it.

How I build a shampoo bar

My Coconut Shea and Neem Tea Tree bars are the oldest kind of cleanser there is: oils turned into a solid bar. Coconut Shea is coconut, castor and shea, with extra shea left in and glycerin kept in the bar, so curls rinse soft, not stripped. Neem Tea Tree is avocado and castor, no coconut, with neem and tea tree for an itchy, built-up scalp.

One honest thing: a bar cleanser runs alkaline by nature. So the bar cleans, and the conditioner after it closes the cuticle. That’s a two-step wash because of the chemistry, not because I’m upselling you.

Which one is which

The everyday wash: the Coconut Shea Shampoo Bar. Normal-to-dry hair and scalp, waves to 4C. Up to 80 washes per bar if you let it dry between them.

The clarifying wash: the Neem Tea Tree Shampoo Bar. Coconut-oil-free, for a dry, tight or itchy scalp and buildup. Use Coconut Shea on the washes in between.

The second half of the wash: the Babassu Detangling Conditioner. Protein-free, pH 4.5 to 5.5, the slightly acidic range where the cuticle lies flat. After any shampoo bar, this is the step that closes the door.

How to use a shampoo bar

• Wet everything.
• Glide the bar along your scalp, or lather it in your palms.
• Fingertips, not nails.
• Rinse cool, condition, done.
• Let the bar dry on its dish between washes.

Tell me: tight, itchy or calm?

Judge your next wash by your scalp, not the bubbles. An hour later, was it tight, itchy or calm? Comment SCALP in the YouTube comments and tell me. I read these myself, and the most-asked questions become episodes.
