Healthy hair begins at the scalp—but it doesn’t end there.
This two-step topical hair care system pairs holi (growth) 84, our clinically-backed scalp treatment, with holi (locks), our reparative leave-in conditioner, to support healthier-looking, fuller, stronger hair from root to tip.
holi (growth) 84 helps create the optimal environment for healthy growth with a powerful blend of Redensyl®, Follicusan®, spermidine, and copper peptides designed to minimize shedding and support visibly denser, fuller hair.
holi (locks) strengthens weakened strands with silk peptides and biomimetic bonding technology while helping to reduce breakage, smooth frizz, detangle, and protect against future damage.
Together, they address two of the most common barriers to healthy hair: compromised scalp health and breakage.

"After just one use, I am a convert. Brought it with me to the spa, knowing I would use its shampoo and conditioner. Unfortunately, my freshly washed wet hair felt dry, coarse, and knotted. I then did an experiment and applied Holi Locks. I could immediately see the shift. The product instantly made my hair silky, smooth and easy to manage. Once it dried, I could see the benefits. It’s easy, lightweight and effective."
"I love this bottle and my first instinct was let me smell the scent because every AN Product has such a unique floral and natural smooth scent . I now use this onto at every wash and it has made my hair is looking silky and feeling so smooth ."
"I’m loving the new holi locks! My hair usually gets easy tangled and frizzy, but after applying it not only was my hair easy to detangle, it dried frizz free. After only a couple of uses my hair is looking so so soft and healthy. This is a new go to and it smells incredible! Amazing formula!!"
"I recently had to cut a significant amount of my hair due to cumulative damage from stress, dry heat, and honestly, not keeping up with trims when I should have. Since incorporating Holi (Locks) Silk Peptide Leave-In Repair into my routine, I’ve noticed a real difference in the texture and feel of my hair once it dries. It feels softer, smoother, and far more manageable. More than anything, it’s renewed my motivation to stay consistent with my hair care regimen. And while great results matter most, there’s something undeniably inspiring about reaching for a product that feels both effective and luxurious."
"I have been waiting for another amazing hair product from Agent. I have tried them all. Currently using the 84 spray. I bought a bottle of this and I love it so much. Makes the hair silky smooth, easy to comb, beautiful to air dry or heat style. Love love love it. Make a travel size!"
"I went lighter for summer and with that, my hair was left very dry and damaged. I could tell the benefits of holi locks after one use. My hair was smoother, moisturized, shinier and was feeling like it did before the bleach job. I have thick yet fine stranded hair and while most products weight it down, this DOES NOT! I cannot recommend this enough. I LOVE IT!"
"What a luxurious and wonderful addition to the agent line of products. My hair is soft, shiny and smells beautiful after each use. The scent is not overwhelming just divine on every way. And it leaves no residue. I love this product!"
"This leave in conditioner is much, much more than ‘just a leave in conditioner. ’ It is a true treatment product. I have struggled profusely with my hair since the COVID, tried nearly every high end product on the market and nothing worked until AN collagen and radiance. This leave in treatment worked the very first time! My hair is color treated (I’m in my 50’s) and damaged. This treatment smoothed and moisturized the very first time. When I say moisturized—from the inside out! I was truly amazed. Each time I’ve used it, my hair has felt and looked better and better. My hair is long and somewhat thick (thanks to Holi 84, mane, radiance, and calm!) and 4 pumps will do me on damp hair. I also put 2 pumps on dry hair (in between wash days) because it helps tame the frizz. The smell to me is divine and smells very high end. I’m excited to continue to see my hair recover, thanks to AN. Highly, HIGHLY recommend this treatment!!"
"It’s beyond my expectations. I have very dry, frizzy hair and when I use this and air dry my hair (I don’t like to use a lot of heat) my naturally wavy hair becomes more curly and is super soft. AND it lasts! Shampoo/conditioner next?! :)"
"This cream feels amazing. Smells wonderful and is rich and thick yet doesn't feel greasy or heavy. I've used it a couple times and my ends feel so much less rough and scraggly. As always, a beautiful formulation and reasonably priced. Excited to use long term and see how my hair looks!"
