Please purchase! Amazing!
Oh my gosh, this is the best serum for your hair! It’s amazing! I have thick,coliy, curly ( very coily and super frizzy! This serum is lightweight, makes your hair shiny, soft and best of all say goodbye to frizzy hair! I’m so excited. All I applied to my hair was the neem detangling spray (amazing too, my hair gets tangled easily and this works like a gem too) and the serum. Blow dried it and my hair turned out amazing! It helps also as a protectant too! This neem active ingredients are healthy, help breakage and it bonds the end’s of your hair. I can’t smell anything with this serum. It doesn’t weigh your hair down. Say goodbye to olaplex number 6! & their serum they make. I only needed the detanglar spray and serum. I’m just over the moon, finally I found it! I also use their blonde shampoo and conditioner I love it too! I can’t say enough great things, except I wish I would have discovered this year’s earlier. I have spent too much money searching for the right products. Redken, olaplex, pureology, Moroccan argan oil and no results. I’m just so excited, oh and it didn’t take me as long to blow dry my hair either, which used to take me an hour, not anymore. I know it’s pricey, but in the end, you will be saving money, because this is how amazing this serum works. Love l’anza products!

Holy Grail for Soft, Strong Hair!
I’ve tried so many hair oils over the years, but L’ANZA Hair Strengthening Oil is on a whole different level. My hair is naturally dry and a bit damaged from heat styling, but just a few drops of this oil leaves it feeling silky, smooth, and noticeably stronger.It’s lightweight, absorbs quickly, and doesn’t leave any greasy residue—which is a huge plus. I use it on damp hair before blow-drying and sometimes on dry ends for a little extra shine and frizz control. The smell is also amazing—subtle and salon-fresh.After a couple of weeks of consistent use, I’ve noticed less breakage and my hair just looks healthier overall. Definitely worth the investment. I’ll be repurchasing for sure!

Best hair serum on the market by far
I will never go without this hair serum! I color my hair at home and my hair is healthier than it’s ever been because I’ve used this serum for the past year. It’s pricey but the bottle lasts forever. My hair is just past my shoulders so 1 pump is all it takes. 10/10

Bleached, thick, wavy hair
This is the best product I have found for my bleached, thick, and wavy hair. I have tried countless and this is the only product that actually makes my hair shiny and soft and manageable without weighing it down and requiring a wash within a couple days. I go nearly a week between washes and it does not oil it down. My hair is however not prone to that, bc it’s so dry from bleaching. It’s worth the cost and the smell is delightful.

Liquid Gold!
This stuff is gold! Super silky and I love that it can be applied before heat. Has worked wonders on my dry hair.

Love the product. Hate the price.
I’ve repurchased this numerous times at this point. Its the only hair oil I like. It doesn’t leave your hair greasy at all but makes your hair super soft and shiny. 4 stars only because I wish it was more affordable.

Wow! Après une seule utilisation déjà mes cheveux sont plus doux et une fois lissés au fer plat, non seulement ils sont très lisses, mais en plus ils n’ont plus l’air cassés! Mes cheveux sont maintenant doux et ont l’air fraîchement coupés! Aucune pointe fourchue! Jamais un produit n’a eu autant d’effet sur mes cheveux si rapidement! Une petite quantité suffit et il protège des outils chauffants! J’adore!!!
