Birchbox Breakdown

The best conditioners perform a necessary balancing act: on one hand, they replenish and hydrate hair; on the other, they encourage healthy volume and bounce on the other. Peter Thomas Roth’s Mega-Rich Conditioner toes the line like a star, restoring even the most parched strands without a smidge of heaviness. You’ll have healthy, frizz-free hair in no time.

How to Use

After shampoo, work a quarter-sized amount through hair. Let it sink in for a minute before rinsing with warm water. Towel dry and style hair as usual.

Leaves hair silky smooth

I absolutely love pretty much every Peter Thomas Roth product I have tried. This conditioner leaves my hair soft and flyaway-free. You don't have to use it every day; every other day works just fine.

Sleek & Shiny

Just like the shampoo, this conditioner left my hair feeling sleek and shiny!!! It's very hard to find conditioner that moisturizes without leaving a greasy residue in my ultra fine hair, but this did the trick! So please with this item!!!

Very moisterizing

I was using some products that dried out my hair. I received a sample of this and it fixed up my hair even when paired with a drying shampoo. I bought a full size right away and have been happily using it ever since. I will very likely repurchase.

An unexpected favorite
Purchased

I actually initially tried this conditioner as a sample that was given in a hotel I recently stayed at, but loved it so much I ended up ordering it from Birchbox after I got so excited to find it available for purchase on this site! This product does what it promises, giving my hair shine and softness without weighing it down. I especially enjoyed this when my hair was much shorter and I was having a hard time adjusting to the new amount of shampoo and conditioner to use.

Leaves hair soft

I really enjoy this conditioner. It leaves my hair feeling soft but not too weighed down, which is important for my straight hair. Nice fragrance, not too strong.
