What it is
The LUX Super Rich Shine Relax Night Care Smoothing Shampoo was designed around a specific insight: that a significant portion of the damage making hair puff and fray happens not during the day but at night, from hours of hair-against-pillow friction. The formula is positioned as a night-care ritual rather than just a daily wash — a shampoo that preps hair to survive sleep rather than simply cleaning it. The base is 80 percent beauty serum (water included, minus preservatives and stabilizers), which is a notably rich ratio for a mass-market shampoo. Hydrolyzed silk and argan oil work as repair and smoothing agents, while lavender extract adds both moisture and the calm, sleep-adjacent scent the line is built around. The fragrance — a composed blend of water lily and lavender — is soft and grown-up, distinctly more spa than floral candy. Reviewers consistently note the foam quality: fine, dense, and easy to work through even thicker hair without needing to double-shampoo.
Ingredients
(1) Hydrolyzed Silk (加水分解シルク): a protein-based repair agent that smooths the hair surface and reduces frizz from mechanical friction
(2) Argan Oil (アルガンオイル): a nourishing plant oil that conditions and adds surface shine without heaviness
(3) Lavender Extract (ラベンダーエキス): a botanical moisturizing agent with a calming, sleep-supportive scent profile
(4) Serum-based formula base (80 percent): a high-moisture carrier that delivers conditioning agents more effectively than standard shampoo bases
(5) Water Lily (睡蓮, via fragrance): contributes the signature fresh, aquatic top note of the line's scent blend

How to use
Use the LUX Super Rich Shine Relax Night Care Smoothing Shampoo as the final step of your evening shower or bath. Wet hair thoroughly, then apply an adequate amount — roughly two to three pumps for medium-length hair — and work into a lather from roots to ends using circular motions at the scalp. Focus on distributing the foam evenly through the mid-lengths and ends, where friction damage tends to accumulate. Rinse thoroughly. For best results, follow immediately with the matching conditioner or tube treatment, concentrating on the mid-lengths and ends. Lightly towel-dry rather than vigorously rubbing, and allow hair to air-dry or blow-dry gently before sleep to reduce overnight friction and tangles.

I bought just the shampoo. The scent isn't too strong, and it's a nice, relaxing scent. It lathers really well, but it does make the ends of my hair feel a bit rough. It doesn't really suit me, so I won't be buying it again.
I had the impression that lavender scents often have a strong, air freshener-like scent, but this one wasn't too strong and combined with the scent of water lilies, it had a fresh, floral scent that was different from the previous LUX scents. After washing, my hair felt a bit rough, but once I applied conditioner, it wasn't so noticeable. The next day, my hair still had a soft shampoo scent.
The shampoo lathers well. The conditioner is easy to apply to your hair, and after rinsing, it's easy to manage. I like the scent.
The shampoo leaves your hair feeling refreshed, but I felt that its cleansing power was too strong for winter. The conditioner is not too heavy and has just the right feel, but it does tend to leave hair prone to bedhead. It leaves your hair soft. The scent is somehow pleasant and faint, and you can still smell it the next morning. I can smell lavender when I use it, but the lingering scent is more floral. It's not overpowering. The feel and scent aren't particularly distinctive, so I thought it would be good for summer use.
My mother bought it for me. It makes my hair so smooth! The shampoo lathers well, and the treatment is packed with nutrients, so it's great. The scent is also very pleasant and soothing.
