A 2-in-1 combines two opposite products into one. Shampoo opens your cuticles to wash it, and conditioner closes those cuticles for softer hair. Trying to do both is like pouring water and gasoline on a fire at the same time.
The average 2-in-1 uses cheap, synthetic ingredients that damage your hair instead of a natural, effective formulation to strengthen and enliven your hair.
2-in-1s coat your hair with silicones that weigh your hair down and make it look lifeless, limp, and dead.
Sulfates in 2-in-1s weaken your hair strands and lead to easier hair breakage especially for those with thinning hair.
Using 2-in-1s regularly will create buildup on your scalp making it itchy and irritated, which can lead to flakes and dandruff.
Since most guys are using the same few 2-in-1 brands, your “Arctic Blast” scented shampoo has probably got you smelling like every bro on the block.
Experts recommend looking for a shampoo and conditioner that treats different conditions like a shampoo that thickens and a conditioner that de-frizzes.
