Update 8/2023
Very impressed with customer service! While this product wasn't my favorite I would absolutely buy from them again but would try something different. They contacted me after this review and offered me exchange or refund. They didn't have what I wanted in stock right then so they gave me a refund. They really acted like they cared about their level of customer support. In a world where the customer is not really treated like a customer anymore I really appreciate them making such an effort.

Original review:
I've had a lot of stress lately and stress has been known to cause thinning hair and I bought this to help with that. This has not helped at all. My hair is thinner than ever and the smell is definitely medicinal smelling. Not natural or earthy though. A bit of a menthol smell. I have it 2 stars because it does clean your hair and it didn't hurt my color any. I'll just stick with stuff in know.

My hair is a 2b naturally curly, and have been using the curly girl method for about 10 months. I've been using this Biotin shampoo and conditioner set for about 7 months now and am still currently using this product. My hair was dry, thin, damaged, and I had abnormally large clumps of hair falling out at the start of using this. 7 months later, here are my observations of this shampoo and conditioner set:

SMELL of BOTH Shampoo and Conditioner:
I don't particularly dislike or like the smell, because it's not fragrant or strong. Usually, I apply a different leave-in conditioner to my hair after every wash anyways. This works well for me because I AM trying to avoid strong fragrances and perfumes in my hair while I've been trying to recover my hair.

SHAMPOO Review:
A small amount of the shampoo lathers up REAL well. I'm surprised that it doesn't have sulfates because it sure suds like it does. But however the ingredients without sulfates are lathering up, what matters is that it's gentle enough but cleans well "“ and it does do that. Sometimes, when my scalp builds up too much oils though (3 days and onwards), the first shampooing is not as sudsy. After I rinse, the second shampooing I apply is SUPER sudsy. And you don't need to use too much shampoo. Play around with the amount to use. Even when I had long hair, I only needed about a quarter size. Now that my hair is shoulder length, I use maybe a nickel size amount or less of shampoo.

Although I've tried the low-poo or no-poo curly girl method (with expensive non-biotin hair wash), it's just never worked well for me when I don't wash my hair more than every 2 days. NOT washing my hair, or not having a clean enough scalp is actually what makes my hair fall out more, in my opinion. So, choosing this shampoo was rather risky at first. I didn't know whether or not it'd be too drying or too stripping of my natural oils if I were to shampoo every 2 days like I wanted. I STILL CAN'T TELL YOU whether or not about that though because I've been using a different nourishing leave-in conditioner every time after I wash my hair.

What I can tell you is that after 7 months of using this biotin shampoo, my hair has been falling out less. It took maybe 2+ months for me to actually notice less hair falling into my drain. It wasn't a dramatic difference though. It was super slow and gradual. I took pictures of my drain every time I washed my hair just to see the difference in hair fall. If I were to compare day 1 and day 80, I'd be able to tell the difference. But I would not be able to tell the difference between day 30 with day 40 or something like that. When I look in the mirror now, there aren't glowing bald spots or widening scalp gaps staring back at me "“ and I'm extremely happy with that.

CONDITIONER Review:

I've been using this side-by-side with the biotin shampoo. Because it doesn't have silicones, I use it on my scalp and only my scalp"¦ for a reason. This conditioner is just not smooth enough (because it doesn't have silicones), nor does it coat my hair evenly enough unless I use a much larger amount than a quarter size. I don't want to waste the conditioner, so I only use a nickel size amount in my scalp, then a different non-silicone conditioner throughout the rest of my hair (one that's cheaper that I don't care about wasting or using more of). I figure there's biotin in the conditioner too so it'd be good for the scalp. Since it doesn't have silicone, there isn't much buildup to the scalp. And since I wash my hair every 2 days, I really don't have much buildup to worry about anyways.

However, I have used this conditioner throughout my whole hair for a short while in the beginning. I don't really like it. Besides feeling like I'm using way too much conditioner from this bottle and thus wasting it, I just didn't feel that it detangled or smoothened my hair enough. Once again, I use a leave-in conditioner after every hair wash, so I can't say how this biotin conditioner is in my hair after drying.

FINAL THOUGHTS:
Overall, I do like this particular brand of Biotin shampoo and conditioner. The biggest highlights for me after using the set for 7 months is that 1. the shampoo feels cleansing enough if I wash every 2 days, 2. the shampoo feels gentle enough for a curly girl (meaning it doesn't feel like it's stripping excessive amount of oils cuz we curly ppl have hair that's drier than straight-haired ppl with no exceptions), 3. the conditioner doesn't build up in my scalp, and 4. it makes me feel better to have a non-silicone biotin conditioner that I can apply directly to my scalp. After 7 months of using this, I don't want to try a different brand because not only am I tired of trying and keeping track of different products every few months, but because I feel like this does work on me.

Full disclosure though, biotin shampoo and conditioner aren't the only things I've been using to help with thickening and healthy hair. I've also installed an Aquabliss shower filter, which has helped my hair immensely as well. I've also been using an Apple Cider Vinegar shampoo and Ryo anti-hair loss shampoo/conditioner once a week or so, which I do not know if it has been helping, but I'm using to just finish it up. So really, I'm using this Biotin Shampoo and Conditioner set 2 times a week. I also haven't applied a heated hair dryer nor any heating elements to my hair for 10 months now, so when I look at my healthy hair, I do think it's really due to allowing my hair grow undamaged from excessive heat. But the thickening of the hair and less hair fall is probably from the biotin and the filtered shower water.

You guys!!! Seriously, I absolutely LOVE the smell!! This is my second time buying this shampoo/conditioner. When I first bought this set, my hair started thickening, getting softer and I absolutely loved the smell. I noticed I had virtually no hair falling to the drain, when usually I could count on getting a small handful of hair each time I washed my hair which was around every 3 to 4 days since I work from home. Some of 1 star reviewers are just crazy and just complaining about the smell, so I really didn't bother to read the bad reviews.

BUT man, I REALLY wish I had. Because when I ran out and purchased this second set, the fragrance was still the same, HOWEVER my hair texture seemed different. It wasn't soft like before, it felt like hay, much like a lot of the 1 star reviewers are saying (yes, I now have read many of their reviews - sorry y'all). AND the worst part is that I started noticing my hair falling to the drain during my shower each time after a shampoo rinse then a conditioner rinse. Unlike before where I had virtually no hair falling out. I don't blow dry, color or put lots of product in my hair, I'm pretty low maintenance. I have used this product this second time around maybe 4 or 5 times waiting for that same hair thickening that happened the first time around right away, still hasn't happened yet. So, yeah, I'm done. Eff this shampoo/conditioner set. And the reason I'm sticking this in the 5 star section is so the person that is like me and never reads the 1 stars because they are in denial, will hopefully read this and not make the same mistake I did"¦sorry I had to click bait you, but I'd rather click bait you and take the heat than you have a big 'ol BALD spot. NOT worth it. This product needs to be called out and REMOVED from the EARTH.

LOVE the shampoo but would like to see large 32 oz pump bottles! My hair is clean and soft...until I use the conditioner. IDK what's with that, but it takes a LARGE amount to get anywhere and my hair is in tangles when finished! Comb out is painful! I can't afford to lose more hair! Please add Keratin to this!!! As soon as I add a keratin conditioner such as NEXXUS Black Rice Keraphix conditioner my hair is silky. My next purchase will be shampoo only.

I love the smell and the clean feeling on the scalp, but after a couple of months my scalp started feeling sensitive, itchy and irritated. I had to stop the product and to started applying a prescribed lotion called metametasone. I think that because I'm very sensitive skin I had this reaction. I can't even dye my hair because my irritating scalp.
