The Surprising History of Shampoo

Nov 8

I recently learned that it was back in the 1930s when the first synthetic surfactant shampoo hit the U.S. market. This “sudsy” product created a whole new way of thinking about hair care. It seemed revolutionary at the time: a lathering shampoo that gave people that “clean” feeling through foaming bubbles. But behind the convenience, this synthetic surfactant shampoo came with a hidden cost.

The lathering formulas stripped natural oils from the scalp, setting off a cycle of dryness that required more products—like conditioners, serums, and oils—to restore softness and shine. It was a cycle that fueled the rise of a multibillion-dollar hair care industry. What these shampoos often ignore, though, is that our scalp naturally produces sebum (oil) to protect and nourish both the scalp and hair. When stripped away too often, hair can become brittle, leading to increased dependency on additional styling products.

Your Scalp: A Super Absorbent Surface

The scalp is highly absorbent due to its dense network of hair follicles, sweat glands, nerve endings, and blood vessels. Chemicals in conventional shampoos, such as sulfates, synthetic fragrances, and preservatives, can be absorbed into the bloodstream quickly through these pathways. For healthier hair, transitioning to a gentler routine that prioritizes natural products can have profound effects.

How to Support a Balanced Scalp

Making a few adjustments can help restore your scalp’s natural balance and reduce the need for frequent shampooing. Here’s a simple routine to try:

Reduce Shampoo Frequency: Washing your hair less often helps the scalp maintain a healthy level of natural oils.
Use Cornstarch as a Dry Shampoo Alternative: Apply a small amount of cornstarch at the roots to absorb excess oil between washes.
Pre-Shampoo Oil Treatments: Oils like jojoba, olive, or coconut applied to the scalp before washing add a protective layer, helping to prevent over-drying.

When shopping for hair products, seek out natural or DIY alternatives rather than those containing sulfates (e.g., sodium laureth sulfate or ammonium laureth sulfate) that can strip natural oils. Common chemicals like synthetic fragrances, parabens, and formaldehyde-releasing preservatives can also weaken and irritate your hair and scalp over time.

Nutrition for Strong, Healthy Hair

A balanced diet can help promote healthier hair growth. Key nutrients for hair health include:

Biotin (found in egg yolks, liver, and walnuts)
Vitamin B5 (from dairy milk, yogurt, avocado, beef, and chicken)
Vitamin C (from citrus fruits, bell peppers, guavas, and kiwi)
Vitamin D (try daily sun exposure, salmon, sardines, and cod liver oil)
