Perfect for dry or split ends!
Yes, the bottle is small, but a little goes a long way. I shampoo scalp, use a good salon conditioner making sure every strand gets conditioner away from just away from scalp. When I rinse, and towel dry, I use a good leave in conditioner all over down to the ends. Then I dry my hair. I use the BioSilk Therapy on all of my ends. And every day I put it on my ends again to keep them sealed and from getting dry or split. I was recommended to do this process from a hairdresser because my hair had gotten so dry. I didn’t think I was able to revive it honestly. The leave in conditioner spray, after the shampoo and conditioner, and the BioSilk Therapy on the ends has made my hair so soft again, and now it’s finally starting to get longer. Loving the BioSilk! ... show more

So tiny
Sooo small.. I will take some ownership to not reading the details closer. I knew it was travel sized but didn't realize it was this small. BUT is smells and feels like the authentic product and I've gotten fraud biosilk before when ordering online so I'm happy. And the screw cap will be so nice so it doesn't spill in my bag like the larger sizes sometimes do. ... show more

My Favorite Hair Serum—Perfect for Travel
BioSilk Silk Therapy has been my favorite hair serum for years. This travel-size bottle is perfect for packing and takes up very little space in my toiletry bag. For longer trips, I may need to bring two bottles, but I love the convenience of the smaller size. It delivers the same great results without the bulk, making it ideal for travel. Highly recommend! ... show more

Excellent product
Excellent product. But this was small for the price. I was looking for a travel size though, so it's OK.

Perfect product
BioSilk made my hair feel incredibly soft, shiny, and smell amazing. After the first use, I noticed less frizz and a much smoother texture. It doesn’t leave the hair greasy or heavy, and a small amount goes a long way. It’s perfect for heat protection and gives the hair a healthy, salon-quality finish. Definitely worth it. ... show more

The product is amazing. Buy the bigger bottle this one is super tiny
This product is amazing. But this little size bottle is ridiculous. Is better to buy the bigger size bottle and put some in a small bottle. It only lasted me 4
