Customers say
Customers find this hair gel provides good hold without build-up and is particularly effective for fine, curly hair, keeping it defined and frizz-free. Moreover, the product receives positive feedback for its quality and ability to create a strong cast. However, the drying ability and scent receive mixed reviews – while some appreciate that it doesn’t flake when dry, others find it very drying, and while many like the mild scent, some compare it to men’s cologne.

Great product!
Best gel I’ve ever used to hold my short, fine hair style in place for hours!

Great for wavy hair!
Iâve been using this product for a few years since I started styling my hair more naturally, itâs a great hard hold gel that lightweight finer texture wavy haired people can use. It gives my hair a great cast and holds my waves for a days. I also use it for my boys hair and it keeps my active 4 & 5 year old sonsâ hair in place all day.Pros: solid cast, great for finer hair textures, use sparsely for best results, no weird scents and can be used for any gender.Cons: very sticky consistency and needs to be emulsified with water before using, and if you use too much it can leave flakes in your hair

I love this stuff for my wavy hair
I love this stuff for my very thick, shoulder-length wavy hair, and have been using for a number of years. I generally use a rinse-out conditioner to “wash” my hair, then apply a leave-in (As I Am Coconut Leave-In Conditioner), and then apply this gel (BioSilk’s Rock Hard Gelee), all before getting out of the shower and towel-drying my hair. Very happy with my waves with this combo.

Good cast, crunches out to soft
Love that this gives a good cast. Nice clear gel, crunches out very easily leaving soft waves and curls. I have type 2b/c waves and curls, I have to manipulate some sections to encourage curls with twisting, some sections curled on their own. I paired with a shea Manila honey yogurt leave in spray- everything was shiny and smooth- no dry frizz. Day 1 no flaking.The smell is okay. Very âsalon productâ smelling, but scent is completely secondary to me if the product does what I hope.Will probably keep. Still looking for a magic gel that gives thick curl clumps, but it may not be possible for my hair type.Plan

Best gel ever for fine, wavy hair
I love this gel so much. It’s got incredible hold, and wavy fine hair needs more hold than you’d think. This stuff doesn’t weigh my hair down or leave residue/stickiness, but it does create a really good cast and then breaks up beautifully when you scrunch it out. My hair stays in defined curl clumps pretty much all day, even when it’s humid. I think people who have had trouble with this gel aren’t properly emulsifying it prior to application. You need to add a little water to your hands and rub it between your palms really well. It will look white and a little frothy when it’s properly emulsified, and then it absorbs into your hair follicles nicely.

Great product, unscrupulous seller.
My Wife and I have used the Biosilk Rock Hard Gelee for years and really like how it holds your hair in place. The only reason I did not rate it higher was because the seller I purchased this product from is very unscrupulous and their product page is very misleading. When I confronted them they just basically ignored my requests. I will but the product again but will NEVER do business with this seller

Best Gel for Curly Hair
Best gel ever! I am so surprised. I have curly hair and have tried soooo many gels but this one is the best. I get a great cast and my hair is less frizzy and shinier than normal. Highly recommend

I love this gel! It has great hold and makes my curls stay looking good for a couple days.

This product gives you whatever level of hold you like, depending on how much you use. Best of all, there is no messy build- up of product in your hair. Curls will last for up to a week. If you want a firm hold, this is for you.
