Both baking soda and soap are alkaline so damaging to both skin and hair, they are also chemicals and arguably as harsh or harsher than regular shampoo, soap is worse than baking soda. There is nothing natural about soap it's not found it nature but made in a factory by chemical reaction. Be aware that harsh shampoos and soaps can cause the scalp to produce more sebum, and it can take a while for that to settle down.
Possibly more gentle and natural is egg yolks (packed with natural emulsifiers), but this can leave hair smelling 'eggy'. Also soap nuts or soapwort extract both of which are mildly acidic like healthy hair and skin - these have been used for personal hygiene since the stone age.
If you use any method that strips away the hair's natural oils (sebum and the structural ones holding the cuticle together and protecting it) you need conditioner or to think carefully about how you replenish and protect hair. Jojoba oil has a vague similarity to one minor component of sebum, it doesn't contain the saturated fatty acids, oleic acid, cholesterol, ceramides or 18-MEA found in hair and sebum.
Aloe and glycerin are both potent humectants, does that suit your dew points/ humidity? Too much humectants can draw too much water to the hair weighing it down. Better natural stylers include okra gel or flaxseed gel, perhaps adding xanthan gum for more hold and/ or magnesium sulphate (epsom salts) for curl boosting. Hydrolysed protein is another natural curl booster - gelatin is the only food source. Anything you DIY or add ingredients to you need to consider a preservative unless you want to be putting bacteria or fungal spores in your hair.
Many many wavies and curlies have success with conditioner only washing, but it can take perseverance for some. It means trying a few different products just as you do with shampoo and working on your technique. A lot of times people make the mistake of choosing a 'moisturising' or depositing conditioner instead of one that simply cleanses gently but effectively.
Also make sure all your other products/ ingredients are compatible with your chosen wash method. It's not just silicones that can build up, but butters, some polyquats, waxes including cetyl esters, mineral oil/ petrolatum. It's fine to alternate conditioner washing with other forms of no-poo. Doing all this my hair is literally 'squeaky' clean when I am done, no residue or grease.
There are some nice largely natural products made by companies like Komaza Care, Spiral Solutions, Sweet Curls Elixirs (new see Facebook) and Jessicurl. Even the CURLS line that is widely available commercially (Target, Walmart) is very natural even claims to be organic.
