Alexandra, your proposed formula is interesting. We have not yet worked with reetha in such an application, we can only give you some suggestions: xanthan gum is in too high a percentage (somewhere around 0.5% would probably be ok) the required amount of lactic acid cannot be estimated beforehand, the pH of the shampoo should be measured at the end and adjusted if needed the total percentage of essential oils is too high and especially in the sage one, the shampoo can liquefy excessively use cosgard at 0.8% considering the nettle macerate and the reetha infusion Good luck!

This formula is suitable for oily hair and if formulated correctly: A: Lavender mild base 10% A: Coconut tenside powder 6% B: Net Nettle macerate 40% B: Nettle powder concentrate 29% (I was thinking to put 2 tablespoons to 500 ml water and boil until it decreases to half the amount) B: Glycerin 9% B: Xanthan gum 2% B: Lactic acid 0.4% C: Cedar Atlas 1% C: Rosemary 1% C: Sage 1% C: Cosgard 0.6% Thank you

thank you

Yes, Diana.

thanks a lot, so all the ingredients added together make 100% (i.e. 250 ml)?

Hello Diana, In the shampoo base it is advisable to include ingredients in a maximum of 10% in total. You can add approx. 5% liquid coconut surfide or foaming surfide. If you want to include vegetable oils, the washing and foaming power and viscosity will be reduced. You can include honeyquat approx. 2% and possibly 2% glycerine (or 4% honeyquat, being dry hair, is perhaps a better choice). Essential/perfuming oils or other actives, 1% at most, total.

Hi, I also got a shampoo base and it doesn't really lather, can I add a liquid surfactant to it? I would like to put honeyquat as a conditioner, a combination of oils (jojoba, coconut, castor and broccoli) glycerin and a perfuming. My hair is a bit dry. I don't know if I have chosen the right ingredients , but I would like it to be both moisturizing and nourishing and not make dandruff.Can you advise me on the quantities and if I need anything extra , and to be even more vascos .For a quantity of 250 ml. Thank you

Hello Gabriela, The shampoo base really doesn't have too great a degreasing effect. The recipe is dedicated for oily hair due to the action of the active ingredients to balance sebum secretion, a process that can take a longer time. A shampoo with high washing (degreasing) power can stimulate increased sebum secretion and so the hair will tend to become more greasy.

Hello, Unfortunately the shampoo does not provide an effective degreasing, although it is recommended for oily hair. What ingredient could I add for a better cleansing sensation? Thank you,

Cristina, the amount of ingredients added in the shampoo base is approx. 9%, and it is quite high and the oregano essential oil is a bit more than necessary, as it is very potent. In our opinion, there is no need to apply an anti-dandruff solution based on essential oils in parallel with this shampoo as there is a risk of scalp irritation. As for the roughness of the hair after washing, you probably also need a hair conditioner) applied only to the strands, not to the scalp if it is oily.

Cristina, let's see exactly what your final formula looks like, what it's made of. Shampoo base ?? % Tea tree essential oil ?? % Oregano essential oil ?? % Urea ?? % Argan oil ?? % Silicon (the simple or the volatile one?) ?? % Marine-Z ?? %

Hello Cristina, Please write us the composition of the shampoo you prepared, what ingredients and how much exactly you included in the shampoo base because from the previous comments we can't figure out exactly.

Hello.Unfortunately hair after washing is very coarse hair after washing as if it has hairspray an it and scalp has matreta the same way I prepared and anti matreta soluatia and spray the root but still not good.What can I do I prepared 1 liter of shampoo.Can I send it to my mil send it to remake WHAT CAN I DO.Thanks.

Hello Cristina! Yes, that can be a good solution. Let us know how it turned out and how your hair and scalp react after a few washes.

Hello.If I put another shampoo base on top of this one which I have added too many essential oils, 10 ml of marine-z would be good (I want to order again).

Cristina, you have used too much essential oils in the formula, of which oregano is very strong, so the scalp can become irritated and dandruff can form. Including silicone is not the best choice for such a shampoo. Unfortunately you can't remedy the shampoo already prepared, but in the future you can consult us on the formula we have devised, so that we can give you some guidance in advance.

I made this shampoo base and I added the following ingredients.marine-z10ml,essential oil of tea-tree 4,5ml,essential oil of oregano 4,5ml,urea 6gr,argan oil 3ml,silicone 7ml.The hair after washing it is very rough when wet after drying it is very fine and beautiful.The problem is that I immediately make a lot of dandruff.What can I do to use it or what to add to it.Thanks I am waiting for your answer

Thank you very much for your reply. Have a good evening.
