Kérastase Densifique Bodifying Shampoo vs Kérastase Densifique Bain Densité Shampoo

Both are Kérastase Densifique shampoos built around hyaluronic acid and a densifying complex, so the real choice is format, not formula. The 250 ml bottle is a standalone shampoo with ceramides and gluco-peptide added for texture and fiber strength, and it suits fine or thinning hair that wants body. The 500 ml pouch is a refill for the Bain Densité bottle, so it only makes sense if you already own that bottle or plan to buy one. Owners rate both highly, but the bottle has far more ratings behind it.

• Choose the Kérastase Densifique Bodifying Shampoo 250 ml if you want a ready-to-use bottle with ceramides and gluco-peptide for texture and strength, and you are not set up for refills.
• Choose the Bain Densité Refill 500 ml if you already use the Bain Densité bottle or will buy one, and you want a larger, lower-waste top-up.
