University of North Carolina researchers found that when Diethanolamine (DEA), a chemical used as a thickening agent in most shampoos, is applied to the skin of pregnant mice, it interferes with their offspring’s normal brain development. DEA blocks absorption of the nutrient choline, which is essential to brain development.
Additionally, the most common chemical compounds in shampoos are straight-chain alkyl benzene sulfonates. Benzene is a chemical that is responsible for Myelodysplastic Syndromes (MDS), oftentimes the precursors to leukemia and many types of cancers.

Most conventional shampoos contain 1,4-dioxane, a highly toxic carcinogen. According to the California Environmental Protection Agency, 1,4-dioxane is known to cause cancer and may cause kidney, respiratory, and neurological toxicity. The Environmental Working Group (EWG) has also stated that 1,4-dioxane is a groundwater contaminant.

I get that people don't like chemicals in their care products, but...don't expect these homemade recipes to work anything like conventional cleansers.

I can verify the science behind this article, however the amounts of these chemicals when used in shampoos are far below the exposure levels in the experiments.
It is prudent to reduce known environmental toxins but just because something (the alternate recipe) contains naturally sourced ingredients, does not automatically mean it is less toxic.
For instance the Rosemary oil (used in the 'natural' recipe) can be toxic if ingested, and should never be used by people with high blood pressure, ulcers, Crohn's disease or ulcerative colitis. The University of Maryland Medical Center advises that rosemary can have interactions with antiplatelet and anticoagulant drugs, ACE inhibitors, diuretics and lithium, and can interfere with certain diabetes medications as well.
Similarly, geranium oil contains terpines and is a diuretic, it has also been reported to be a skin irritant in rare cases. The purported antispasmodic nature of geranium oil would suggest that it should be avoided during pregnancy.
So, it would be wise to use the most minimal amounts of surfactants when washing, just enough to 'do the job' with minimum exposure. I, personally prefer unscented glycerine soap, even for hair, and rinsing well.
Additionally, stripping off the natural oils of the skin too thoroughly may actually promote dermatitis.

Pine tar soap is the only personal hygiene product anyone should ever need. Wash your whole body and hair with it. i can't rate it highly enough. My skin has never been better since using it.
