Is this discontinued?!? Say it isn’t so!

This is my absolute favorite conditioner I have ever used and discovering it hasn’t been available for months is devastating. Please bring back this product! This is the number one kiehl’s product for me and many others. The smell of this conditioner! The result on my hair! This product became a must have when it was at Equinox and I’ve been buying it now for 3 years. Can’t believe I may not be able to buy it again!

Hope it is not discontinued!

I’ve been a loyal Kiehl’s customer for decades and hope this conditioner is not discontinued! It is by far my favorite product and the reason I have stayed with Kiehl’s for so long.

Silky, smooth hair

The best conditioner for wavy hair! I am brand loyal when it comes to this product. If they ever discontinue it I’ll have to buy up every last bottle!

Discontinued!!!!!!!!??????

Oh NO! Both my daughter and I use this daily and can't imagine, with so many positive reviews, WHY it is being discontinued. It is such a staple in our hair-care routine, what are we supposed to use now!? #badidea

Manage your frizz

I’ve used this leave-in conditioner for years. It leaves my hair smooth and less frizzy. Highly recommended.

RIP Formula 133

Well… like many of you I have been a Formula 133 devotee for decades. To me this is Kiehl’s #1 product by far. Alas, Kiehl’s was bought by L’Oreal and 133 has been discontinued. Why Kiehl’s has not take the time to advise its devoted customer base about this is beyond me. Sad.

Love it

My must have leave-in-conditioner. Hair is soft and healthy; my cruls are springy. Be careful with 1st few uses because, as with any hair product, too much will leave hair feeling greasy and heavy. But, this is the only haircare product that I use after every single hair wash - as a conditioner and a base for whatever other hair styling products (or not) I use
